An edition refers to the number of art prints created from one image. Open editions refer to a print that may be produced an indefinite number of times. Limited editions refer to a finite number of prints that are made from one image. Limited editions are numbered by the artist with two numbers separated by a slash.
The first number indicates the sequence in which the print was made. The second number indicates the total number of prints in the edition. A print numbered “10/50” is the tenth print made in an edition of fifty. Once the fifty prints in the edition have been produced, the edition is retired and will not be printed again.
Limited editions also include a number of artist’s proofs that are retained by the artist for her own use or that are sometimes sold by the artist after the limited edition has been exhausted. Artist’s proofs are designated “AP” and numbered in the same manner as limited edition prints.
