Remscheid: Vice-Versand, 1968
3 x 12 x 6 cm approx wooden chess board that folds into a box, ordinarily to contain chess pieces and act as a traveling game, but this box is empty. There are labels on exterior and interior lid: the exterior label reads: “Optimistic Box no. 3/ So much the better if you can’t play chess.” Interior label reads: “You won’t imitate Marcel Duchamp./ Robert Filliou”. One of a supposed “unlimited edition”, nonetheless scarce as it was never remade after the original run. Very good condition although outer label slightly cut on left. Ref: Verz. No. 151.
