The king is a pyramid, the queen is a cone, the bishop is a flagon, the rook is a cube and the pawn is a sphere. Man Ray, the American icon of Dada and Surrealism who has more than 100 works in MoMA's collection, made his now-classic chess set with found objects from around his studio. The knight, perhaps the most striking piece, is represented by a scroll-shaped violin finial. Chess set and board sold separately.
