Ben Vautier Gesture Piece (Fold/Unfold) New York City, USA: Fluxus, 1968 Offset, 7.6 x 5.1 cm (paper, folded), 15.2 x 20 cm (paper, unfolded)
"I did a piece in Ben Dieu which I proposed for Fluxus. Folded paper with 'unfold' on the corner edge and then you unfold until you get to 'fold' in the center, and then you refold. He told me it was too much like a George Brecht." - Ben Vautier, 1984.
The work had actually been produced by Fluxus almost two decades prior to Vautier's knowledge of it, for inclusion in the Flux Year Box 2.
