The sticker series “Das ist kein Sporthocker” (engl. “This is not a Sport-hocker”) is a homage to René Magritte’s mas­ter­piece “Ceci n’est pas une pipe” (engl. “This is not a pipe”). The shape of the objects, which are obvi­ously no “Sporthocker”, always refer in one or the other way to shape of the sport­ing device.
