A photograph of Marcel Duchamp, taken in Munich in 1912, serves more than a hundred years later as the starting point for seventeen drawings. Commissioned by the conceptual artist Rudolf Herz, Parisian street painters appropriated Duchamp's radically expressionless photographic portrait, each adding their own unique artistic signature. Duchamp's time in Munich in particular led to his decision to free himself from any form of artistic signature, the "patte", or "paw". Herz's thesis: Duchamp's photograph anticipates the development revealed through his revolutionary idea of readymades. Marcel Duchamp. La Patte is an ironic response to Duchamps decision and reflects in a playful and associative way the fundamental turning point in his work. Texts by Antje von Graevenitz and others outline the art-historical context.
