Political and Economic Context

Political and economic context asks what systems of power, policy, labour, trade and money caused a collectible to exist in its particular form. It goes beyond dating an object. It examines who authorised or financed production, which materials were available, what rules shaped wording or design, who could obtain the object, how it moved through markets and why particular examples survived. A tax stamp, substitute fitting, censored passage, export label, altered emblem or unusually high original price may all be material evidence of those systems.

The collector's task is not to attach a broad historical event to every unusual feature. Context is strongest when it connects a specific observation to a documented condition and survives comparison with other explanations. War may make a cardboard substitute plausible, but so might an economy range, later repair or regional supplier. Political and economic research therefore works as disciplined interpretation: begin with the object, identify the relevant place and period, build a credible causal hypothesis, and then test it against records and comparable examples.

Collector scenario: the supposedly rare wartime version

A collector compares two examples of the same product. One has a heavier component, brighter finish and full-colour box. The other uses thinner material, simplified printing, a plain insert and an unusually high price sticker. One seller calls it a rare wartime economy issue; another dismisses it as a damaged or incomplete copy.

Political and economic context gives the collector a disciplined route through the disagreement. Were the relevant materials restricted? Did the maker announce a substitute specification? Was the product sold in a regulated market, repriced during inflation or assembled locally because of import controls? Do independent examples repeat the same combination of features? The historical context makes an explanation plausible, but the object, comparisons and records must still prove it.

The controlling principle

Context should explain evidence. It should never be used to rescue a claim that the physical object and documentary record do not support.

Objects are products of overlapping systems

Every collectible sits within several systems at once. The same object may carry a state symbol, be manufactured by a private contractor, use a rationed material, travel through an export agent and later acquire an institutional inventory mark. Good research keeps those layers separate before explaining how they interact.

Political authority

Monarchies, republics, empires, occupying powers, colonial administrations, local authorities and revolutionary governments can determine symbols, titles, language, borders, currency and authorised imagery.

Questions to ask

  • Which authority governed the place and date connected with the object?
  • Was the issue official, commercial, satirical, oppositional or merely patriotic?
  • Could inherited symbols or old stock have remained in use during transition?

Economic structure

Guild, workshop, factory, state enterprise, command economy, consumer market and informal production systems shape cost, scale, standardisation, labour and access.

Questions to ask

  • Was the object luxury, institutional, subsidised, mass-market or promotional?
  • Who could realistically afford it at the time?
  • Did credit, instalment purchase or state allocation widen access?

Law and regulation

Patents, tariffs, taxation, censorship, rationing, standards, licensing, export control and safety rules can leave physical or documentary traces.

Questions to ask

  • Which jurisdiction applied the rule?
  • When did it begin, change or end?
  • Was the mark applied at manufacture, import, distribution or sale?

Production and labour

Workshop practice, subcontracting, factory conversion, mechanisation, strikes, migrant work, forced labour and wartime mobilisation may explain changes in quality, location or timing.

Questions to ask

  • Who performed the labour that the maker's name obscures?
  • Did production move or become subcontracted?
  • Could labour disruption explain delay or variation?

Distribution and exchange

Ports, wholesalers, department stores, mail order, military supply, colonial trade, export agents and grey markets determine where versions appear and where they survive.

Questions to ask

  • Was this intended for domestic, export, military or institutional use?
  • Does the packaging identify a distributor rather than the manufacturer?
  • Could later trade or collecting explain its present location?

Historical disruption

War, revolution, occupation, depression, sanctions, currency collapse, decolonisation and regime change can affect every stage of an object's lifecycle.

Questions to ask

  • Is the timing close enough for the disruption to be relevant?
  • What direct mechanism links the disruption to the observed feature?
  • Is there a simpler commercial or technical explanation?

Political forces that shape collectible evidence

Political context is not limited to overtly political memorabilia. It can shape ordinary household goods, packaging, maps, textiles, toys, ceramics, printed matter and company identities. The question is how authority and ideology became visible in a specific object.

Government, succession and regime

Changes in ruler, constitution, state name or territorial authority can alter portraits, titles, seals, heraldry, maps, official languages, calendars, insignia and currency.

Evidence to examine

Look for altered titles, overprints, erased symbols, transitional seals, renamed institutions, revised borders and continued use of inherited stock.

What it may mean

A discontinued emblem may date design or stock, not necessarily manufacture. Transitional use can be genuine rather than anachronistic.

Collector risk

Dating solely from a political symbol can create false precision, especially where old plates, packaging or forms remained in circulation.

Revolution, occupation and political transition

Rapid change can produce overprinted money and stamps, repurposed uniforms, altered seals, revolutionary badges, underground print, concealed objects and renamed manufacturers.

Evidence to examine

Typography, paper, printing process, exact slogans and documented issuing bodies matter because dramatic revolutionary material is frequently reproduced.

What it may mean

Erasure, overprinting or reuse may be the primary historical feature rather than damage or later tampering.

Collector risk

A dramatic political story can overpower contrary material evidence. Period plausibility is not the same as authenticity.

Empire, colonial administration and unequal exchange

Colonial systems shaped extraction, production, exhibitions, missionary collecting, military removal, export craft markets and the transformation of ceremonial material into commodities.

Evidence to examine

Research excavation records, military service, dealer routes, permits, shipping documents, institutional inventories and originating-community knowledge.

What it may mean

An object may have been made for local use, adapted for colonial buyers, collected under unequal circumstances, seized, excavated or transferred through official administration.

Collector risk

Legality under an imperial system does not by itself resolve present-day title, ethics, restitution or community authority.

War and mobilisation

Conflict can redirect factories, ration materials, simplify packaging, replace components, introduce military codes and generate both official and improvised objects.

Evidence to examine

Compare wartime directives, maker records, catalogues, dated advertisements and repeated examples rather than relying on appearance alone.

What it may mean

Substitute materials, emergency repair and field adaptation can be historically meaningful evidence rather than simple condition loss.

Collector risk

Not every rough or simplified example is wartime production, and an object made during war is not automatically proven to have been used in the conflict.

Propaganda, protest and political communication

Posters, pamphlets, badges, toys, ceramics, school material and ephemera may recruit, persuade, intimidate, fundraise, suppress dissent or shape collective memory.

Evidence to examine

Identify the precise issuing body, intended audience, distribution method and relationship between national organisations, local branches and commercial imitators.

What it may mean

Political material is evidence of what producers wanted audiences to believe, not necessarily evidence that its claims were true.

Collector risk

Modern interpretation can assign meanings that a symbol did not have in its original setting or ignore later appropriation by another movement.

Censorship and prohibited expression

Restrictions may explain blacked-out passages, revised editions, coded imagery, pseudonyms, concealed signatures, foreign editions and unusually low survival.

Evidence to examine

Establish who imposed the restriction, its geographical reach, date of enforcement and whether uncensored export or private versions existed.

What it may mean

An apparently incomplete publication may be a formally censored state rather than a damaged copy.

Collector risk

Later defacement, collector alteration and genuine censorship can look similar without edition comparison and provenance.

Propaganda is authentic evidence even when its claims are false

Political material should be read on several levels: what it depicts, what its producer wanted an audience to believe, what actually occurred, how the original audience responded and how later collectors or institutions reframed it. A poster can be an authentic period object and still communicate a selective, distorted or fabricated account.

This distinction is central to catalogue wording. Record the object as evidence of political communication and intention. Do not silently convert its message into a factual description of the event.

Economic forces that shape production, access and survival

Economic context explains more than original price. It can reveal who could acquire an object, why a maker changed materials or location, why a version was exported, why apparently disposable material survives and why market rarity differs from production rarity.

Wealth, class and purchasing power

Original price becomes meaningful only when compared with wages, household income, rent, ordinary goods, local living costs and access to credit.

Evidence to examine

Use contemporary wages, catalogues, advertisements, household budgets and instalment terms alongside inflation calculations.

What it may mean

An object with a modest nominal price may still have represented weeks of income; an apparently elite product may have been sold through weekly payments.

Collector risk

A modern inflation conversion answers a different question from affordability and should not be presented as a complete measure of historical value.

Inflation, deflation and currency reform

Price instability may produce overprinted prices, smaller quantities, cheaper materials, barter, hoarding, new denominations, dual pricing and rapid catalogue revision.

Evidence to examine

Record the currency notation, denomination, sticker layer, catalogue date and whether old stock could have been repriced after manufacture.

What it may mean

A decimal or reformed-currency label can date sale or handling without necessarily dating the object beneath it.

Collector risk

Dramatic denominations, especially on hyperinflationary notes, do not automatically indicate rarity because worthless money was often retained as a curiosity.

Austerity, rationing and resource control

Government allocation of metal, timber, paper, fuel, textiles, rubber and imported materials can create utility marks, substitute components and restricted designs.

Evidence to examine

Check regulatory dates, exemptions, export priorities, material specifications and whether restrictions continued after the headline end of rationing.

What it may mean

Reduced ornament or lighter construction may be a regulated response rather than ordinary cost-cutting.

Collector risk

Austerity is often used as a generic explanation. The relevant material and industry must actually have been affected.

Taxation, tariffs and import controls

Duties and protectionist rules can alter dimensions, country marks, assembly location, packaging, price, component sourcing and commercial routes.

Evidence to examine

Identify the legal period, jurisdiction, exemptions, application stage and whether marked stock remained in use after the rule changed.

What it may mean

A local assembly or country-specific version may be a legitimate response to tariff or local-content rules rather than a counterfeit.

Collector risk

A duty stamp may date import or sale rather than production, and smuggling or grey-market routes can complicate an apparently official geography.

Sanctions, embargoes and blocked trade

Restrictions can cause substitute materials, unofficial imports, neutral-country routing, rebranding, component shortages, grey markets and imitation products.

Evidence to examine

Use customs notices, government orders, shipping records, company correspondence and catalogues showing withdrawn or unavailable lines.

What it may mean

Absence from an official national catalogue does not prove absence from the market; informal circulation may have continued.

Collector risk

Later sellers may convert ordinary regional scarcity into an unsupported 'banned' or 'sanction-era' premium story.

Industrialisation, patents and commercial control

Mass production, patents, registered designs, licences and monopolies shape standardisation, model ranges, serial systems, supplier networks and geographic versions.

Evidence to examine

Patent records can establish claims, inventors and earliest possible dates, while catalogues and production records show whether a design actually reached market.

What it may mean

Mass production does not mean absolute identity; tool wear, batches, regional factories and subcontractors can create legitimate variation.

Collector risk

A patent date is not automatically a manufacture date, and 'patent pending' may remain on products for a long period.

Advertising and manufactured demand

Trade cards, premiums, branded displays, sample books, promotional toys and loyalty rewards often began as disposable commercial tools rather than collectibles.

Evidence to examine

Determine whether the item was sold, given away, conditional on purchase, nationally distributed, numbered or restricted to selected retailers.

What it may mean

Modern scarcity may come from low survival rather than low distribution, while 'limited edition' may have been a marketing device rather than meaningful restriction.

Collector risk

Collector enthusiasm can repeat a maker's scarcity language without establishing actual production, distribution or survival numbers.

Economic scarcity and survival

Scarcity can arise because few were made, few reached a region, most were consumed, examples rarely enter the market or high-grade survivors are exceptional.

Evidence to examine

Use production records, distribution evidence, institutional holdings, auction frequency, condition data and category-specific survival patterns.

What it may mean

Production scarcity, distribution scarcity, survival scarcity, market scarcity and grade scarcity are different claims.

Collector risk

Calling an object 'rare' without naming the kind of scarcity hides weak evidence and makes comparison difficult.

How context becomes visible in the object

The strongest research moves back and forth between the historical record and the physical object. These evidence axes help a collector organise observation without assuming that every difference has one cause.

Materials and construction

Substitute alloys, plated rather than solid metal, reclaimed stock, lightweight board, synthetic fibres, local materials and emergency components may reveal pressure on supply.

What it may mean

Material change can support a contextual explanation only when the date, place and industry match documented conditions.

Collector risk

Scientific testing or specialist comparison may be needed because repair, restoration and counterfeiting can produce similar appearances.

Size, weight and contents

Smaller packages, thinner walls, reduced metal content, fewer components, narrower margins and miniature formats can reflect regulation, inflation or economy positioning.

What it may mean

Measured differences are more useful than visual impressions and should be compared across dated examples.

Collector risk

Shrinkage, trimming, loss, incomplete sets and manufacturing tolerance can imitate deliberate reduction.

Decoration and finish

Plain finishes may reflect austerity, mechanisation or lower market tier; elaborate decoration may signal patronage, diplomatic display, luxury or export prestige.

What it may mean

Finish is evidence of intended market and production priorities, but rarely identifies cause by itself.

Collector risk

Cleaning, fading, restoration loss and unfinished goods can be mistaken for original simplicity.

Marks, wording and symbols

Royal warrants, tax stamps, utility marks, union labels, patent numbers, military codes, export marks, political slogans and regime titles can be highly diagnostic.

What it may mean

The collector should establish who had authority to apply a mark, where it was applied and during which dates.

Collector risk

Copied marks, retrospective nostalgia and continued use of old dies can weaken apparently precise dating.

Packaging and retail layers

Packaging may preserve price, currency, distributor, language, border, safety, rationing and promotional evidence that the object itself does not show.

What it may mean

Original packaging is a historical source, not merely a value-enhancing accessory.

Collector risk

Object, insert, box, overlabel and price sticker may come from different moments and should not be treated as one date layer.

Repairs, adaptations and removals

Improvised components, stitched repairs, converted military goods, erased insignia, repriced packaging and repurposed containers may document disruption and continued use.

What it may mean

A repair may be evidence of historical scarcity or ownership practice rather than only a condition defect.

Collector risk

The same intervention may also be later collector work. Documentation and material examination remain essential.

Distinctions that protect collector judgement

Design, manufacture and sale

Do not collapse

A design date, patent date, manufacture date, packaging date and retail sticker date may all differ.

Collector practice

Assign each clue to the layer it actually dates and preserve overlapping ranges where certainty is limited.

Political imagery and official issue

Do not assume

A ruler, flag, slogan or patriotic colour does not prove state authorisation.

Collector practice

Identify the issuing body and distinguish official, commercial, satirical, hostile and commemorative production.

Nominal price and affordability

Nominal price

The amount printed on a label or invoice in contemporary currency.

Affordability

The wage burden, household access and working time required for the intended buyer to obtain the object.

Wartime manufacture and wartime use

Manufacture

The object was produced during a conflict or under wartime regulation.

Use

The object is demonstrably connected with military, civilian or institutional activity in that conflict.

Historical importance and rarity

Importance

The object documents or is demonstrably connected to a significant person, event, system or community.

Rarity

The object is uncommon in production, distribution, survival, market appearance or high grade. Importance does not prove rarity.

Legal acquisition and ethical acquisition

Legal title

A claim assessed under applicable ownership, export, import and limitation law.

Ethical position

A broader judgement involving coercion, unequal power, sacred status, community authority and responsible stewardship.

Provenance, ownership and coercive transfer

Politics and economics often explain gaps or abrupt changes in ownership. War, persecution, forced sale, confiscation, nationalisation, colonial removal, migration, bankruptcy and inheritance taxation can all move objects through collections and markets. A transaction may be formally documented yet still have occurred under coercive conditions.

Terms that require investigation rather than repetition

forced sale or distress sale

enemy or abandoned property

nationalised collection

wartime deposit

restitution or expropriation

confiscation or seizure

expedition acquisition

colonial gift

missionary collection

dealer stock with unexplained source

Domain boundary

Historical context identifies the political and economic conditions that may have shaped transfer. The detailed chain of ownership, documentary gaps and source evaluation belong primarily to provenance research. Questions of lawful title, export, import, sanctions and restitution may also require specialist legal advice.

Do not treat a contextual explanation as a substitute for provenance documents. It identifies where the chain deserves closer scrutiny.

Category-specific applications

The same contextual method applies across collecting fields, but the diagnostic evidence differs. These examples show where the political or economic question is likely to enter each category.

Coins and currency

Research focus

Issuing authority, legitimacy, debasement, occupation, emergency issues, inflation, reform and demonetisation.

Collector application

Metal content may reveal fiscal stress; overprints may mark political transition; huge denominations may be common rather than rare.

Stamps and postal history

Research focus

Territorial control, independence, occupation, postal rates, censorship, overprints and administrative transition.

Collector application

A surcharge or overprint may date a short-lived authority, but forged political overprints require exact comparison.

Medals and militaria

Research focus

Conflict, eligibility, unit, rank, contracts, mobilisation, political rehabilitation and post-war disposal.

Collector application

A medal's official criteria and named recipient matter more than broad association with a campaign.

Books and printed ephemera

Research focus

Censorship, paper control, taxation, literacy, propaganda, print runs, suppression and revised editions.

Collector application

Missing text may indicate censorship rather than damage; cheap ephemera may have high documentary significance.

Toys, games and popular culture

Research focus

Consumer income, political education, military culture, licensing, export markets, material restriction and advertising.

Collector application

A simplified game may reflect an economy line, wartime restriction or regional production; context must distinguish them.

Ceramics, glass and commemoratives

Research focus

Royal and state events, patronage, tariffs, fuel costs, export policy, mass consumer markets and political symbolism.

Collector application

An unrealised coronation or abandoned event date can produce genuine period objects rather than later fantasies.

Textiles and clothing

Research focus

Rationing, sumptuary rules, imported fibres, labour, uniform systems, class display and colonial supply chains.

Collector application

Utility marks and reduced fabric use can be regulatory evidence, while later alterations may imitate economy construction.

Archaeological and ethnographic material

Research focus

Excavation law, colonial removal, export permits, military acquisition, dealer networks, community ownership and illicit trade.

Collector application

A documented old collection is not enough; the route out of the source community or country may still require investigation.

A practical political and economic research sequence

This is a genuine sequence rather than a checklist to complete in any order. Each stage limits the risk of building a powerful historical story around an incorrectly described or wrongly dated object.

1

Describe before interpreting

Record dimensions, weight, materials, construction, wording, marks, symbols, colours, condition, packaging and alterations. Photograph each evidence layer separately.

  • What is directly observable?
  • Which parts appear original, applied later, altered or uncertain?
  • What have you measured rather than merely noticed?
2

Establish the date range and evidence layers

Use maker history, marks, patents, typography, materials, catalogues, political titles, currency and geographic names to create a range rather than force a single date.

  • What dates the object itself?
  • What dates the packaging, label, import or sale?
  • Could old stock or later repricing explain the mismatch?
3

Identify the jurisdiction and market

Determine the relevant country, territory, occupation zone, colonial authority, local government and intended market. Rules vary by place as well as by time.

  • Where was it made, distributed and sold?
  • Was it intended for domestic, export, military or institutional use?
  • Does the present location reflect later ownership rather than original distribution?
4

Build the contextual timeline

Place government changes, conflict, laws, tariffs, rationing, currency reform, company events, factory movement and product appearance on one working timeline.

  • Does the proposed cause precede the observed change?
  • How long did transition or enforcement actually take?
  • What overlaps or exceptions complicate a clean break?
5

Form a specific causal hypothesis

Connect one observable feature to one plausible mechanism: shortage to material substitution, tariff to local assembly, regime change to altered emblem, inflation to repricing or censorship to revised text.

  • What exact feature requires explanation?
  • What documented pressure could have produced that feature?
  • What ordinary alternative explanations remain?
6

Test against records and comparable objects

Check whether the feature repeats across independent examples and whether contemporary documents describe the change. Compare earlier, later, domestic, export, premium and economy versions.

  • Is the pattern repeated or unique to one object?
  • Was the rule actually enforced in this industry?
  • Would a repair, replacement or mixed set fit better?
7

State fact, inference and confidence separately

Write the observed fact, relevant context, comparative evidence, interpretation and confidence as distinct parts. Use terms such as documented, strongly supported, probable, possible, unverified or contradicted.

8

Preserve the evidence trail

Record source title, archive reference, page, URL, access date, relevant quotation or fact, how it applies and any unresolved question. Revisit the conclusion when new evidence appears.

Evidence hierarchy

Evidence strength depends on the claim. An official directive may prove that a rule existed, but not that a particular maker complied on the assumed date. A catalogue may document a model, but not every production variation. Use sources together and record precisely what each one establishes.

Strong primary evidence

Contemporary records created by authorities, businesses or participants closest to the relevant transaction, rule or production decision.

  • legislation, official gazettes and wartime directives
  • customs records, tax schedules and trade statistics
  • company ledgers, contracts, catalogues and price lists
  • invoices, shipping manifests, export licences and patents
  • dated advertisements, photographs and documented provenance

Strong secondary evidence

Research that critically evaluates primary sources and places them within established scholarship.

  • museum collection catalogues
  • peer-reviewed articles and specialist monographs
  • economic and institutional histories
  • scholarly exhibition catalogues and catalogue raisonnés

Supporting evidence

Useful material that may identify leads, examples or market history but usually needs corroboration.

  • dealer catalogues and auction archives
  • collector society publications and oral histories
  • price guides, specialist forums and comparative listings

Weak when used alone

Claims that can preserve a lead but should not carry a firm historical conclusion without independent support.

  • seller stories and undocumented family recollection
  • modern promotional copy and copied auction descriptions
  • undated online images and collector lore
  • dramatic labels such as 'battlefield', 'royal' or 'banned' without records

Turn context into a disciplined interpretation

Observed fact

The object uses painted steel fittings rather than the brass fittings found on earlier documented examples.

Historical context

Government controls and military demand restricted civilian access to non-ferrous metals during the relevant period.

Comparative evidence

Contemporary catalogues and independently dated examples show the transition from brass to steel fittings within a defined production range.

Interpretation

The fittings are consistent with documented wartime production rather than an isolated later replacement.

Confidence

Probable, pending confirmation from factory or regulatory records that directly cover this maker and model.

Myth versus reality

Myth

A wartime date explains every cheaper material or rough finish.

Reality

Budget ranges, supplier variation, export versions, repairs and counterfeits can produce similar features. Wartime context must fit the material, place and documented timing.

Myth

Inflation conversion tells us what an object was worth to its original buyer.

Reality

Inflation shows changing purchasing power, while wages, working hours, household income and access to credit reveal affordability and class reach.

Myth

Political imagery proves official issue or direct historical use.

Reality

Commercial souvenirs, hostile satire, nostalgia and later reproduction may use the same symbols. The issuing body and distribution evidence matter.

Myth

A major event automatically makes related objects rare and valuable.

Reality

Major events often generated huge quantities of souvenirs and propaganda. Historical importance, survival, demand and financial value must be assessed separately.

Myth

An old documented acquisition is therefore ethically uncomplicated.

Reality

Formal purchase records can coexist with forced sale, colonial power imbalance, illicit export, sacred status or absence of good title.

Myth

A dramatic seller story is acceptable when it is historically plausible.

Reality

Plausibility is only a research lead. Claims of battlefield recovery, covert use, royal ownership or prohibited circulation require unusually strong evidence.

Documentation checklist

Record the contextual conclusion in a form that a later owner can test, revise or separate from the underlying identification.

  • Political jurisdiction, governing authority and relevant administration
  • Relevant conflict, regime transition, movement or state event
  • Official, commercial, satirical, oppositional or commemorative status
  • Issuing body, manufacturer, subcontractor, distributor and intended market
  • Original price, historical currency, wage comparison and credit terms
  • Tax, duty, rationing, tariff, import, export or sanctions evidence
  • Material substitution, economy construction or wartime production evidence
  • Censorship, propaganda purpose, licensing or regulatory marks
  • Provenance risk periods, export documentation and restitution concerns
  • Observed facts, contextual sources, interpretation, confidence and unresolved questions

When specialist input becomes proportionate

Title, restitution and cultural-property risk

Seek specialist legal or provenance advice where records suggest forced sale, wartime seizure, colonial removal, illicit excavation, nationalisation, sacred status or uncertain export.

Collector risk

Authenticity, legal title, lawful export, ethical acquisition and culturally appropriate ownership are related but not interchangeable questions.

Scientific material questions

Consult a conservator or materials specialist when a contextual claim depends on alloy, fibre, paper, pigment, adhesive or manufacturing analysis that cannot be resolved visually.

Collector risk

Destructive sampling, cleaning or disassembly can damage the object and erase the very evidence being investigated.

High-value or market-sensitive attribution

Use a qualified specialist where political association, wartime status, censorship, rarity or export-market identity would materially change value, insurability or saleability.

Collector risk

Market premiums often follow an attractive story before the evidence is settled. Commercial interest is not independent confirmation.

Sensitive communities and contested interpretation

Where objects relate to living communities, coercive labour, human remains, sacred use, discriminatory propaganda or traumatic events, research may require culturally informed advice and careful language.

Collector risk

Historical explanation should not turn harm or inequality into decorative provenance or collector theatre.

Key takeaways

  • Political and economic context explains how power, law, labour, trade and money became material features of an object.
  • Context should begin with observation and produce a testable explanation, not a dramatic story fitted after the fact.
  • Assign each clue to the layer it dates: design, manufacture, packaging, import, sale, ownership or later handling.
  • Keep importance, rarity, affordability, legality, ethics and market value as separate judgements.
  • The strongest conclusion links a specific feature to a documented historical condition and records the remaining uncertainty.
