A man has admitted writing on a Mark Rothko work at the Tate Modern in London, but insists he is not a vandal. The writing on the bottom-right corner of the piece appears to read: "Vladimir Umanets, A Potential Piece of Yellowism."
Today, Mr Umanets, who is originally from Russia, claimed he had written on the painting, saying:
Some people think I'm crazy or a vandal, but my intention was not to destroy or decrease the value, or to go crazy. I am not a vandal."
