The artwork part of a famous series of three artworks by Joseph Beuys, Günther Uecker and Imi Knoebel. The artists decided that each of them would create a symbol for creativity. Beuys created his „intuition box“ with the handwritten „Intuition“ inside – the spectator should gather his creativity in this box. Uecker created the multiple „Do It Yourself“ with a hammer hanging freely on two nails on a board. Knoebel created his empty canvas frame (stretcher), the spectator shall add the artwork by himself in his mind.
