Robert Filliou believed in creativity rather than art, and saw himself as a creator of ‘anti-objects’. His hands-on, nomadic, deceptive works made from many different materials reflect Filliou’s idea of art as a game, but a serious one. His participation in the French resistance, his studies in Political Economy and his interest in Buddhism were channelled into his Principle of Poetic Economy. And his desire to de-institutionalise art was expressed through his Galerie Légitime, an itinerant gallery concealed inside a hat that displayed his own works and those of other artists. This catalogue includes essays by Sylvie Jouval, Jean-Hubert Martin, Heike Van Den Valentyn, Michel Mollet and Jean-Clarence Lambert, as well as a bibliography compiled by Jürgen H. Meyer and a timeline devised by Michel Giroud.
