AP - Artists Proof
An Artists Proof is when the printmaker makes a preliminary print that is not one of the offical edition. Commonly an Artists Proof is made as a test of the printing plate, and several may be made before producing the final print edition.
Generally a Print will signed in the lower right corner, titled in the middle and numbered in the bottom left corner. If a print is an Artists Proof, the artist will write AP in the bottom left corner instead of an edition number.
