pusenkoff's painting "said duchamp", in which he integrated an image of mona lisa into his work for the first time, was created especially for this exhibition. it shows a smiling frank sinatra as a reminiscence of readymades of marcel duchamp and the mona lisa. george pusenkoff explains: "actually, the picture was thus created for a very special place on this wall and became a key work for the entire installation." in 2008 the installation "the wall" was shown for the first time in the west on the occasion of a comprehensive art exhibition in the kunstmuseum bochum "la condition humaine".
