Andy Warhol’s concept of art expressly included the reproduction, the multiple. Yet the unique work of art did not lose its value, even in Warhol’s Factory. Ever since he began making his famous portrait prints in the 1980s--most of which were commissioned--his prints were carefully limited and signed for his wealthy buyers. For 40 years Jörg Schellmann has been collecting multiples and editions. His portfolios of Warhol works are now sought-after collector’s items. This publication presents the more than 100 trial proofs that were produced under the aegis of the Edition Schellmann und Klüser from 1980 to 1987. Printed on rag paper, and as veritable individual works of art, they are particularly valuable today. Characteristic of these unique pieces of art are the outlines hand-drawn by Warhol, which elevate the print out of the territory of the halftone and color planes and into the realm of "painting."
