Authorised
The maker had permission from the relevant manufacturer, publisher, artist, estate, museum or rights holder. Authorisation addresses the right to produce; it does not prove age, rarity, quality or original-period status.
Legitimate Reproductions
A legitimate reproduction is an intentionally produced later version of an earlier object, image, publication, design or artefact that was authorised, honestly described or lawfully made for purposes such as sale, commemoration, education, preservation, display or use. It can be entirely genuine as a reproduction while not being the original object it reproduces.
That distinction makes legitimate reproductions both helpful and hazardous in authentication. They can preserve inaccessible evidence, provide known comparison material and reveal how production changed. They can also lose their labels, acquire artificial age, be combined with original components or be represented under an identity they were never made to claim. The collector's task is therefore not to ask only whether an object is real, but to determine exactly what it is, when and by whom it was made, how it relates to the source, and whether its present description remains honest.
The governing authentication question
Do not begin with "Is this real?"
Begin with "What exactly is this object claimed to be?"
Authentic does not always mean original. A reproduction can be authentic to its own manufacturer, licence, edition and date while being inauthentic if represented as an earlier original. Authentication must test the claim at the correct level.
Orientation
Legitimacy is not one single quality
Collectors often use legitimate as though it settles every question. In practice, several different forms of legitimacy may apply, and each answers a different question.
Honestly represented
The object was sold or marked as a reproduction, replica, facsimile, reprint, later edition or comparable category. Honest representation can exist even when the maker was not the original producer.
Lawfully made
The production complied with the applicable copyright, trademark, design-right or contractual position. Legal manufacture and collector authentication remain separate questions: a lawful replica can still be falsely sold as an antique original.
Authentic to its own issue
The object is genuinely what it claims to be within the later category: the correct producer, licence, period, edition, materials, construction and packaging, without undisclosed alteration.
A reproduction may satisfy one dimension and not another. It may be unauthorised but openly described; authorised but later misrepresented; lawful but poorly documented; or authentic to a later edition but altered after manufacture. Record the dimensions separately rather than allowing one favourable word to substitute for the full identity.
Classification
The principal forms collectors encounter
The vocabulary varies between fields, but the categories below help locate an object within a production and claim history. None of the labels alone establishes value, age or honesty.
Facsimile
A reproduction intended to simulate both the content and the physical appearance of a source, often very closely.
Common in books, manuscripts, maps, posters, photographs, catalogues, comics, game manuals and historical documents. Signatures, stamps, folds, annotations and damage may be reproduced as part of the image rather than newly applied to the copy.
Reprint or republication
A later printing of previously published material, sometimes retaining the original artwork and wording while changing paper, binding, printing method, identifiers or copyright information.
A reprint can be fully authorised and collectible while still being incorrectly described if represented as a first printing or original issue.
Official reissue
A later release by the original company, a successor or a current rights holder.
The word official establishes a relationship with the rights holder. It does not establish original-period manufacture, first-issue status or equivalence with the earliest production run.
Replica
A reproduction of the form, appearance or function of another object, usually three-dimensional although usage varies by collecting field.
Replicas may be licensed or unlicensed, exact or interpretive, functional or display-only, permanently marked or visually difficult to distinguish. The term is descriptive, not automatically condemnatory.
Museum or study reproduction
A reproduction made or licensed for access, education, preservation, exhibition, handling, interpretation or retail.
Museum association may support the stated origin of the reproduction, but it does not turn the reproduction into the original object held by the institution.
Authorised later edition
A later production approved by an artist, studio, publisher, estate, foundry, manufacturer or other rights holder.
The edition may be authentic to its own authority and period while remaining materially, historically and commercially distinct from a lifetime, first-state or original-period example.
Replacement component
A later-made part intended to replace missing, damaged or unusable packaging, labels, inserts, accessories, hardware or functional components.
A replacement may be entirely legitimate and useful, but it changes the originality and sometimes the completeness of the assembled collectible. Disclosure is essential.
Reconstruction
A recreated object based on plans, photographs, fragments, measurements, moulds, tooling, archaeological evidence or comparable surviving examples.
A reconstruction can have substantial educational or cultural value without being a surviving original. Its evidential basis and degree of conjecture should be recorded.
Collector scenario
The object stays the same; the claim changes
A collector buys a well-made museum-shop replica. It is sold in labelled packaging with a receipt and leaflet identifying the source object and production date. At that point there is no deception: the replica is exactly what it claims to be.
Years later, the packaging is lost. A new owner sees genuine age, attractive wear and a convincing form. The inherited record says only "old ceremonial object". Nothing physical has changed, yet the authentication risk has increased because the evidence that carried the reproduction identity has drifted away.
The experienced collector asks two separate questions: what is the object? and how is it now being represented? The object may remain a legitimate museum reproduction while the present description becomes mistaken or deceptive.
Evidential value
How legitimate reproductions help authentication
A documented reproduction is not merely a lesser substitute for an original. It can be an essential reference population that clarifies which features continued, which changed and which apparent authenticity signs were copied deliberately.
It reveals which features are not exclusive to originals
Evidence
A copied signature, logo, stamp, date, serial format or copyright line may appear perfectly on a legitimate reproduction because it was deliberately carried forward.
Meaning
The presence of a familiar feature is useful only when its evidential meaning is understood. A printed signature proves that the source image contained the signature, not that the individual reproduction was hand-signed.
Collector risk
Treating reproduced marks as independent evidence can create false confidence and inflated attribution or autograph claims.
It supplies known comparison material
Evidence
A documented reproduction can be measured and compared for dimensions, weight, materials, colour, typography, mould lines, printing screens, binding, fasteners, internal codes and packaging.
Meaning
Known later issues form a second reference population. They help distinguish features shared across issues from features specific to an original production run.
Collector risk
A poorly documented or altered reproduction is a weak reference specimen. Its date, source and integrity must be secure before it is used as a standard.
It exposes generational copying
Evidence
Successive scans, photographs, casts or mould generations may lose fine lines, compress tones, enlarge halftone dots, crop borders, repeat dust marks, copy folds or distort proportions.
Meaning
A counterfeit may have been derived not from the original, but from a known legitimate reproduction. Matching reproduction-specific defects can reveal the intermediate source.
Collector risk
A close visual match to an original image does not establish original manufacture when the image may have passed through several copying generations.
It explains suspicious-looking but genuine later features
Evidence
Modern paper, digital printing, new safety wording, revised dimensions, different polymers, altered moulding or updated company information may belong to an authorised reissue.
Meaning
The object may be authentic to a later issue even though it is inconsistent with the original-period specification.
Collector risk
Collectors can wrongly condemn a legitimate reissue as an illicit fake when they compare it only with the first issue and ignore documented production chronology.
It helps build a production chronology
Evidence
Originals and later legitimate issues may record changes in artwork, logos, factory location, mould repairs, barcodes, identifiers, warnings, packaging dimensions or rights holders.
Meaning
Authentication becomes a sequence model rather than a single original-versus-copy test. Each issue can be placed within a documented manufacturing history.
Collector risk
Without chronology, a feature introduced on a later issue may be mistaken either for proof of fakery or for evidence that the object is earlier than it is.
It separates content authenticity from object authenticity
Evidence
A facsimile may preserve the wording, image, music, map, photograph or data of an original with great accuracy while using a later physical or digital carrier.
Meaning
The informational content may be faithful while the object itself is not the original artefact or original-period manifestation.
Collector risk
Accurate content can distract from the date, material identity and production history of the carrier being collected.
Failure modes
How an honest reproduction becomes an authentication hazard
The risk often arises after manufacture. Context disappears, components are changed, marks are suppressed or a later owner promotes genuine age as proof of a much earlier identity.
Context is lost
Packaging, certificates, receipts, museum labels or release literature disappear. An honest reproduction then enters the secondary market without the material that once disclosed its status.
Warning signs
- The object is unmarked but known examples were identified through packaging.
- The seller relies on inherited description rather than period documentation.
- A loose object is presented with more certainty than the surviving evidence supports.
Reproduction marks are removed or concealed
A base is replaced, a modern margin trimmed, a copyright page removed, a mark ground away, a surface repainted or the object relined or repackaged.
Warning signs
- Localised disturbance where a known mark should appear.
- Dimensions smaller than documented examples without a convincing production reason.
- A mismatch between surface wear and the area carrying identity information.
The reproduction is artificially aged
Staining, abrasion, artificial foxing, oxidation, fading, simulated craquelure, dirt, smoke, distressed packaging or old hardware are added to suggest earlier manufacture.
Warning signs
- Age effects are visually dramatic but materially shallow or inconsistent.
- Wear appears in places that handling would not naturally affect.
- Old-looking surfaces sit over modern construction evidence.
A genuinely old reproduction is promoted as a much older original
A nineteenth-century facsimile or early twentieth-century museum replica may possess genuine age, wear and provenance while still reproducing a much earlier object.
Warning signs
- The argument proves age but not original-period identity.
- The provenance begins after the supposed original production date.
- The object's construction is consistent with an old reproduction category.
Original tools or old materials create false confidence
Later objects may use original moulds, plates, dies, negatives, archived artwork, antique timber, old paper, obsolete stock or original spare components.
Warning signs
- Evidence dates a material or tool but not the particular impression, casting or assembly.
- The description substitutes 'from the original mould' for a production date.
- Old components are presented as proof that the complete object is original-period.
Original and reproduction components are mixed
An original body may be combined with reproduction packaging, copied paperwork, replacement accessories, restored surfaces or documents belonging to another example.
Warning signs
- Different components tell incompatible manufacturing or ownership stories.
- Completeness is claimed for a set assembled from mixed-period parts.
- Paperwork identifies the type but not the individual object.
Boundary discipline
Reproduction, counterfeit, fake and restoration are not synonyms
Authentication becomes unreliable when every non-original object is called fake. The terms describe different relationships between manufacture, derivation, alteration and representation.
- Reproduction
- A later object made to reproduce an earlier one. It may be authorised or unauthorised, disclosed or undisclosed.
- Copy
- A broad neutral term for an object or image derived from another object, design or source.
- Counterfeit
- An object made or presented to appear to be the authentic product of another maker, rights holder, issue or period.
- Fake
- A broad collector term for an object whose represented identity is materially false.
- Forgery
- An object, mark, signature, document or artwork made or altered to create false authorship, attribution or authority.
- Fantasy piece
- An object in a historical or product style that was never produced in the claimed original period or line.
- Pastiche or homage
- A new work intentionally imitating or referring to an earlier style without necessarily claiming original identity.
- Restoration
- Intervention on an original object to stabilise, repair or improve it. Extensive work may approach reconstruction, but restoration is not automatically reproduction.
The decisive distinction is object identity versus representation. A legitimate reproduction does not become a fake merely because it resembles an original. It becomes deceptively represented when it is falsely dated, attributed or described; paired with fabricated provenance; altered to suppress its identity; or priced on the basis of an original claim it cannot support.
Examination
Evidence to examine and what it can actually prove
Evidence should be read as a combination. Each area can support or weaken a claim, but no single mark, material or document should carry the entire conclusion without testing its association and limitations.
Marks and identifiers
Evidence
Reproduction wording, licence notices, copyright dates, edition numbers, trademarks, country-of-origin marks, safety statements, barcodes, ISBNs, stock codes, web addresses, mould identifiers and company names.
Meaning
Marks can positively identify a later issue or set a date boundary. Their location, method of application and consistency with documented examples matter as much as their wording.
Collector risk
A single mark is never self-validating. Marks can be copied, forged, transferred, removed or paired with the wrong object.
Materials
Evidence
Paper fibre and coating, board, plastics, pigments, inks, adhesives, thread, cloth, timber, metal, ceramic, foams, magnetic media and electronic components.
Meaning
Material evidence can show compatibility or incompatibility with a claimed period, maker, factory or production run.
Collector risk
A material merely existing at the claimed date is not enough. Old materials can be reused, and modern reproductions can be made from period stock.
Manufacturing method
Evidence
Printing, moulding, casting seams, tool marks, stitching, binding, machining, soldering, welding, painting, finishing, assembly order, fasteners and cutting method.
Meaning
External appearance may be copied closely while internal or underside construction preserves evidence of later manufacture.
Collector risk
Comparison based only on artwork or outward shape can miss the most diagnostic evidence.
Dimensions and weight
Evidence
Measured size, thickness, mass, density, scale and component proportions compared with several documented examples.
Meaning
Differences may indicate mould shrinkage, photographic resizing, trimming, rebinding, revised tooling or changed materials.
Collector risk
One published measurement or one comparison object may not represent normal production tolerance or known variants.
Typography and printed detail
Evidence
Letterforms, spacing, line breaks, punctuation, registration, halftone structure, ink density, trapping, fine-line clarity, cropping, printer errors and colour separations.
Meaning
The wording may be copied correctly while the production process and image generation reveal a later issue or a copy derived from a reproduction.
Collector risk
High-resolution digital reproduction can look convincing in listing photographs while behaving differently under magnification.
Packaging and associated components
Evidence
Card stock, folds, tabs, glue, staples, warning text, distributor labels, shrink-wrap, date codes, inserts and internal supports.
Meaning
Packaging can identify the issue and preserve disclosure that is absent from the object itself.
Collector risk
Original packaging can contain a reproduction object, and reproduction packaging can surround an original object. Examine each component independently.
Provenance and documentation
Evidence
Receipts, catalogues, advertisements, museum invoices, manufacturer records, licences, photographs, correspondence, inventories, shipping records, auction history and exhibition records.
Meaning
Documentary evidence can support who made the reproduction, when, under what authority and how the current object entered the collection.
Collector risk
Documentation is a claim-bearing object in its own right. It may be fabricated, copied, altered, misassociated or too general to identify the specific item.
Scientific examination
Evidence
Ultraviolet and infrared imaging, radiography, microscopy, X-ray fluorescence, Raman spectroscopy, fibre, pigment, chemical, metallurgical or dating analysis where proportionate.
Meaning
Testing can establish material composition, reveal hidden construction and exclude impossible dates or techniques.
Collector risk
Scientific results usually answer narrow material questions. They do not automatically identify the producer, edition, provenance or truthfulness of the sales description.
High-risk details
Copied signatures, edition numbers and certificates
These features often look authoritative because they resemble direct evidence. In reproductions they may instead be copied content, later additions or documents that authenticate only a limited claim.
Facsimile signatures
Ask whether the mark is physically applied to this copy or printed as part of the same image as the surrounding content. Compare repeated examples, surface relief, ink behaviour, halftone structure and whether the mark extends into photographically copied areas.
A reproduced signature can be entirely legitimate while carrying no autograph value.
Numbered editions
A notation such as 17/500 may identify an authorised edition, a later dealer number, an uncompleted edition, a fabricated limitation or even a number copied identically onto counterfeits.
Authenticate the edition's existence, numbering style, format, producer, stamps and production records. Limited does not mean old, original, artist-made or valuable.
Certificates
Check the issuing entity, format, numbering, security features, date, object description and whether the certificate is contemporaneous and correctly associated with this example.
A genuine certificate for an authorised reproduction authenticates that claim; it does not convert the reproduction into the original source object.
Complex editions
Original tooling, posthumous production and later authority
Original tooling does not fix the production date
A later authorised object may use original moulds, plates, dies, negatives, archived artwork, masters or historical machinery. That continuity may make the later issue physically close to the original and important in its own right.
The correct question shifts from "Is the mould genuine?" to "When was this particular impression, casting or assembly made?" Tool authenticity is not the same as object chronology.
Posthumous editions require explicit scope
Determine whether the work was conceived during the creator's lifetime, who authorised and supervised later production, whether original moulds or designs were used, how the edition was limited and marked, and whether lifetime and posthumous examples are distinguished in the market.
A posthumous object may be genuine to its authorised edition while remaining materially, historically and commercially different from a lifetime example.
Decision framework
A five-level authentication hierarchy
Work from broad identity toward the truthfulness of the present description. A reproduction can pass the first four levels as a genuine, complete authorised issue and still fail the fifth because it is advertised as an original.
Level 1
Category
Is the object an original, later production, reprint, replica, restoration, reconstruction or mixed object?
Level 2
Authority
Who produced or authorised it: the original maker, a successor, rights holder, museum, artist, estate, independent maker or an unknown producer?
Level 3
Date and issue
Which production run, printing, state or edition does it belong to: original issue, early reissue, anniversary edition, posthumous production or modern facsimile?
Level 4
Integrity
Is the example complete and unchanged, or does it contain replacement parts, altered marks, restored surfaces, substituted packaging or associated paperwork?
Level 5
Representation
Is the listing, label, catalogue entry or owner description accurate at the level established by the evidence?
Practical workflow
How to examine a suspected reproduction
The safest workflow proceeds from the claim to comparison, then to alteration risk and a conclusion no broader than the evidence permits.
1
Record the claim exactly
Write down what is actually being asserted before examining the object. Separate maker, authority, date, edition, material, originality, completeness, provenance and condition rather than reducing the claim to 'real'.
- What object or issue is this said to be?
- Who is said to have produced or authorised it?
- What date or production period is claimed?
- Which parts are claimed to be original?
2
Identify known legitimate reproductions
Search manufacturer and publisher records, museum catalogues, archived retail listings, collector references and reliably documented examples. The objective is to establish whether a later issue exists and how it was originally disclosed.
3
Build a comparison model
Compare the claimed original, known reproductions and the object under examination across size, weight, material, marks, construction, printed detail, packaging, finish and codes. Use more than one reference example where possible.
4
Look for positive reproduction evidence
Do not search only for errors or defects. Identify features that affirmatively place the object within a documented later issue: a changed warning, known mould revision, specific paper, later identifier, altered scale or issue-specific packaging.
5
Test whether marks are integral
Determine whether signatures, dates, labels, stamps and edition numbers were manufactured with the object, applied later, copied photographically, transferred, replaced or removed.
6
Examine alteration and component risk
Look for trimmed margins, disturbed bases, erased wording, repaired surfaces, substituted components, reproduction packaging, married paperwork and artificial ageing. Record each component separately.
7
Reconcile provenance with the physical object
The ownership story and the manufacture must be chronologically compatible. A claimed early acquisition cannot explain a component, material or edition introduced decades later.
8
State the conclusion narrowly
Use the smallest conclusion the evidence supports. Prefer 'consistent with the authorised 1998 facsimile edition' to an unqualified 'genuine'. State what remains unknown and which evidence would change the conclusion.
Documentation
Record the reproduction as precisely as an original
Reproductions need careful records because their appearance may invite later confusion. Use separate fields so that one broad authenticity label does not conceal authority, date, disclosure or component differences.
| Record field | Suitable values or wording |
|---|---|
| Object type | Original, reproduction, facsimile, replica, reprint, reissue, reconstruction, restoration or composite. |
| Authority | Authorised, licensed, museum-produced, manufacturer-produced, estate-approved, independent, unauthorised or unknown. |
| Date relationship | Contemporary with the source, later, posthumous, commemorative, modern or undetermined. |
| Disclosure status | Permanently marked, packaging marked, documentation only, unmarked, mark apparently removed or unknown. |
| Component originality | All original to this issue, original with replacement parts, reproduction with original parts, mixed, reconstructed or undetermined. |
| Authentication conclusion | Confirmed, probable, consistent with, inconclusive, inconsistent with or falsely represented. |
Preserve disclosure evidence
- Photograph reproduction marks, dates, licences, codes and issue wording.
- Keep boxes, labels, receipts, certificates, leaflets and release notes associated with the record.
- Record when reproduction status depends on packaging or documentation rather than a permanent object mark.
- Repeat the reproduction wording prominently when selling, lending or transferring the object.
Separate component states
- All-original object and packaging for the identified issue.
- Original object with disclosed reproduction packaging.
- Reproduction object placed in original packaging.
- Original and reproduction components mixed together.
A reproduction box may be useful for protection or display, but it must not create the impression of untouched original completeness.
Conclusions
Write an authentication result that can survive transfer
A useful conclusion identifies the later object positively, states its relationship to the source, separates components and marks, and names uncertainty rather than hiding it behind the word genuine.
Authorised facsimile
The item is an authentic example of the 1976 authorised facsimile edition. It is not an original printing of the 1890 publication. The copied inscription forms part of the printed facsimile and is not an original autograph.
Why this wording works
It identifies the later issue positively, distinguishes it from the source and explains the evidential status of the signature.
Original object with reproduction packaging
The figure is consistent with original-period manufacture. The box, insert and instruction leaflet are modern reproductions. The assembled set should not be described as complete in original packaging.
Why this wording works
It authenticates components separately and avoids allowing genuine packaging style to create a false completeness claim.
Older museum replica
The object is a genuine museum-produced replica dating from approximately 1930-1950. Its age and institutional origin may make it collectible, but it is not the archaeological artefact represented.
Why this wording works
It preserves the reproduction's own age and significance while maintaining the boundary with the much earlier source object.
Altered reproduction
The object appears to derive from a documented authorised reproduction, but the reproduction wording on the base has been mechanically removed. Its present appearance is therefore misleading.
Why this wording works
It separates the legitimate origin of the object from the later alteration that changed how it could be represented.
Issue remains inconclusive
The item is consistent with the maker's design but cannot presently be assigned securely to either the original issue or the documented later reissue. Shared tooling means mould detail alone is insufficient.
Why this wording works
It avoids overclaiming and identifies the precise limitation that prevents a stronger attribution.
Market judgement
Read impressive phrases as prompts, not conclusions
Secondary-market language may contain a true fragment while leaving the decisive questions unanswered. Translate each phrase into the evidence it would need to support.
museum qualityfrom the original mouldauthorised editionofficial replicaarchive editionvintage reproductionperiod copyafter the originalin the style oforiginal reproductioncollector's reissueexact facsimileestate approvedfrom the same factoryusing original materials
For example, from the original mould does not reveal when this casting was made, whether the mould was modified, who authorised the production, what material was used, how many examples were produced or whether the object was permanently marked as later.
Replace the phrase with a claim matrix: authority, date, issue, material, tooling, disclosure and integrity. Only then can the wording be judged as informative, incomplete or misleading.
Domain boundaries
Know when the question has moved beyond reproduction status
Authentication
Establishes what the object and its components are, who produced or authorised them, when they were made, and whether the current description is accurate.
Condition and grading
Evaluate wear, damage and state only after the issue and component identity are clear. Genuine age on an old reproduction is condition evidence, not proof of an earlier original identity.
Preservation and conservation
Decide how to stabilise, store or treat the object without removing marks, packaging or surfaces that carry authentication evidence. Do not clean or test destructively merely to make a quick identification.
Provenance and valuation
Provenance supports history but must be reconciled with manufacture. Valuation follows correct classification: some reproductions are scarce and collectible, but their value belongs to the later category rather than the source original.
Specialist threshold
When to stop routine collector examination
Escalation is appropriate when the cost of error, risk of damage or technical ambiguity exceeds what careful non-invasive comparison can resolve.
- The distinction materially affects value, insurance, title, restitution, tax, lending or sale.
- Testing may be destructive, invasive or likely to damage packaging, finishes, bindings or original assembly.
- The object combines original and reproduction components whose treatment requires conservation judgement.
- Marks appear removed, transferred, forged or concealed and the alteration cannot be assessed safely by routine inspection.
- Original tooling, posthumous editions, foundry practice, artist estates or specialist production histories make ordinary comparison unreliable.
- Scientific testing is proposed without a clearly defined question or without suitable reference data for interpretation.
Define the specialist question before commissioning work. Ask whether the proposed examination can distinguish the original issue from the later issue, what reference material is required, whether the result will be probabilistic, and what the test cannot establish.
Collector perspective
A reproduction can become collectible in its own right
Later reproductions may develop independent significance through age, discontinued manufacture, limited distribution, museum association, craftsmanship, cultural importance, an early licensing history, an unusual process or connection to an exhibition or event. A genuine 1970s museum reproduction may be more desirable than a recent copy of that reproduction, and an early licensed issue may be rarer than some original-period mass production.
Authentication should therefore establish the correct collecting category rather than treating reproduction as synonymous with worthless. Precision protects both ends of the market: it prevents a later object being overvalued as an original and prevents a significant reproduction being dismissed because it is not the source.
The collector's core rules
- Authenticate the claimed identity, not merely the appearance.
- Separate originality, authorisation, age, condition, completeness and market value.
- A reproduction can be genuine to its own maker, licence, edition and production period.
- An authorised reproduction is not thereby an original-period object.
- Copied signatures, stamps and annotations may be images of evidence rather than evidence applied to the individual copy.
- Original tools, designs or materials do not establish when a particular object was produced.
- Examine mixed objects component by component rather than forcing a single real-or-fake label.
- Treat certificates, packaging and provenance as evidence that must itself be tested and correctly associated.
- Describe legitimate reproductions positively, precisely and without implying inferiority or originality.
- The deception often lies in the later representation, not in the object's original manufacture.
Final principle
Legitimate reproductions help authentication because they provide a documented second population against which originals, later editions and deceptive copies can be compared.
The strongest conclusion is rarely just real or fake. It is a precise statement of what the object is, who made or authorised it, when it was produced, how it relates to the source, what has been altered, which components belong together and whether the present representation is honest.
