Mark Rothko painting vandal says its more valuable now

A man who claims to be Umanets says he defaced a famous Mark Rothko painting with black marker at London's Tate Modern gallery, ABC News reported.

The painting, Black on Maroon, was defaced by a visitor to the Tate Modern on Sunday.

Police said a man wrote on the painting with a black marker "Vladimir Umanets 12" and "a potential piece of yellowism."

As GlobalPost reported, it is likely a reference the conceptual art blog www.thisisyellowism.com.

The man who claimed to be Umanets told ABC News: "I am not a vandal or some frustrated man. I did not destroy this picture. I did not steal anything."

"I really believe that eventually, this canvas, with my signature will have a higher value than Rothko's other paintings. Not immediately, but in several years," he said.

Umanets said no one tried to stop him after he defaced the painting and that he had also considered defacing a painting either by Pablo Picasso, Jackson Pollock or Marcel Duchamp, ABC reported.

"I went into the Tate with a permanent black marker to inscribe a painting that I personally like the most. After looking at all of his painting, I realized I like 'Black on Maroon' the best," he said.
