Eric C. Jacobson, Hamburg. Ever since the 1960s, Andy Warhol time and again questioned the uniqueness of artworks (and the concept of the unicum) with his serial works. In the era of reproduction this entailed a profound extension of the hitherto widely accepted understanding of art. Since the late 1970s, however, the artist began to undermine his own concept: Alongside his serial prints he turned to the unique artwork and made portraits of famous people. These works were usually created in a serial printing process in combination with the artist personally painting over them or painted prime coats. This, for instance, produced double portraits, which are based on the same motif but vary due to Warhol's selectively applied overpainting on the one hand and their different base colours or additives (such as diamond dust) on the other. Coming full circle, the once serial work thus became unique again. In this manner Andy Warhol also created these two portraits of Eric C. Jacobson (1937-2003). As a designer of unique pieces of furniture, the son of a Swedish paper manufacturer and a mother from Hamburg quickly established himself as a member of a group of creatives around Jil Sander and Wolfgang Joop. His designs were exceedingly popular with wealthy private customers. Also, his invitations to the midusmmer celebrations in Stockholm, Sweden, were legendary. Famous regulars among his guests were, for instance, the Princes of Thurn & Taxis, tennis star Björn Borg, and actor Thomas Hellberg.Always seeking a close alliance with the fine arts, his friends included Georg Baselitz, Markus Lüpertz, as well as Andy Warhol. The two of them had already been friends for several years when the idea for these portraits arose. It must have been due to this fact that - by means of his famous Polaroid camera - the iconic pop artist achieved such a brilliant rendering of the designer's personality, which he later immortalised in his best manner on these two canvases. As a matter of fact, Warhol insisted on handing over the works to his friend in person, but asked Jacobson to invite 'only beautiful and interesting people' on this occasion. Thus, on this evening, the guests present at the designer's pre-war apartment in Hamburg included Jil Sander, Princess Ingeborg of Schleswig-Holstein, and Dieter Giesing, director of the Thalia Theater
