Naef Bauhaus 32-Piece Chess Pieces with Optional Chess Board. Josef Hartwig's Bauhaus Design Masterpiece is as much about mathematics as it is about chess. This game of chess with clean lines is classically characteristic of the timeless Bauhaus style. Naef's chessmen, designed in 1923, have characteristically reduced forms which, in contrast to commonly used figures, are symbols based purely on the function and form of the maneuver of each piece.Have fun!Doxin
