Ask what vintage means here
Request the seller’s basis for the date or period: an acquisition record, dated label, documented provenance or comparison with a reliable catalogue. Keep an approximate claim approximate.
Wear is evidence of condition, not a calendar
Fading, dust, splits, oxidation and surface marks may be relevant to condition, but none independently establishes when an object was made. Deliberate distressing and long storage can also complicate appearances.
Look for a complete object record
Review front, sides, back, top and base, plus dimensions and any labels. Ask whether repairs, overpainting, cleaning or coatings are known. Save the listing description and images with your purchase record where permitted.
Separate enjoyment from certainty
You can value an object’s form and presence without forcing a precise date or maker. Pay for the evidence and object in front of you, not for an unsupported story.
