Raoul Ubac - Derriere le Miroir No. 161

Original lithograph, executed for Derriere le Miroir, no 161, 1966. Published in Paris by Maeght. There is text on verso. Alexander Calder (; July 22, 1898 – November 11, 1976) was an American sculptor known both for his innovative mobiles (kinetic sculptures powered by motors or air currents) that embrace chance in their aesthetic, and static "stabiles" monumental public sculptures. He didn't limit his art to sculptures; he also created paintings, jewelry, theatre sets and costumes. Calder preferred not to analyze his work, saying, "Theories may be all very well for the artist himself, but they shouldn't be broadcast to other people."
