Man who defaced Tate Modern's Rothko canvas says he's added value; Guardian, 10/7/12

Ben Quinn, Guardian; Man who defaced Tate Modern's Rothko canvas says he's added value: "On Sunday night, a man who identified himself as Vladimir Umanets, and answering a phone number provided for an exhibition of "yellowism", said he was responsible for the incident at the Tate Modern and had done so in order to draw attention to what was going on in contemporary art. "I believe that if someone restores the [Rothko] piece and removes my signature the value of the piece would be lower but after a few years the value will go higher because of what I did," he said, comparing himself to Marcel Duchamp, the French artist who shocked the art establishment when he signed a urinal and put it on display in 1917."
