The Proof is in the Provenance
Art provenance is the history of a particular artwork, from its creation to the present. When purchasing a newly created artwork on the primary market—that is, when buying it directly from the artist or from the artist's gallery as part of the first exhibition of such work—the history of the piece is clear. However, when acquiring artworks that are being resold by the initial or a subsequent purchaser (also known as secondary-market sales), the issue of provenance becomes particularly important to the collector.
