In addition to a major essay by Vittore Baroni that traces the history of artist stamps, several artists wrote about their work or the network of artists stamps. The main section contains photographic reproduction of artists stamps. In addition, the book inludes a chronology of first editions, selected exhibitions from 1974 to 1999 and a bibliography.Baroni proposes the following definition for Artistamp: 1) it was concxeived by the artist, 2) it was produced by or at the instruction of the artist who conceived it, 3) it is a print, preferably on gum paper, 4) it is produced in multiples, most often in several rows and columns on a single sheet which is then, possibly, perforated, 5) it is produced in an edition, preferably signed and numbered, 6) it gives some indication of the imaginary or actual issuing authority, and 7) it is a work of art.Felter mentions that the first artist stamp action was done by Yves Klein who affixed 3500 "blue stamps" to a postcard announcements of his exhibitions in the late fifties. The French postal service cancelled the stamps causing a great scandel. However, Klein reached an understanding with a postal worker, paid the postage, and tipped the worker to cancel the stamps. -- Source of annotation: Marvin or Ruth Sackner.
