Full detail for one artwork: attribution, medium, dimensions, edition structure, provenance, seller, and every individual impression that can be bought with its own price and availability. A numbered edition has one entry per impression — including artist proofs (AP), printer proofs (PP), and the bon à tirer (BAT), which are separate objects from the numbered run and usually priced differently. Attributes are as stated by the seller, and a null means unspecified rather than estimated. Also returns image URLs to show the buyer. A signed URL is TEMPORARY: honour its expires_at and re-fetch rather than caching or redistributing it. An image marked permanent is the work’s public copy — reduced and watermarked by Fold — with no expiry. Use this before presenting a work to a buyer, and quote the impression label exactly as given.
