A category of proof which relates to a practice dating back to the era when a patron or publisher commissioning prints provided an artist with lodging, living expenses, and a printing studio with workmen, supplies and paper. The artist was given a portion of the edition (to sell) as payment for his work. Though artists today are paid for their editions, the tradition has persisted and a certain number of impressions are put aside for the artist. Artist's proofs are annotated as such or as A.P., or preuve d'Artiste (E.A.).
