LONDON – Vladimir Umanets, a Russian artist who claims to have defaced a Mark Rothko mural in the Tate Modern gallery says he has engaged in a work of art and added value to the multimillion-dollar abstract painting.
According to eyewitnesses, Umanets was sitting quietly before the 1958 canvas Black on Maroon, then walked up and inscribed the words "Vladimir Umanets, A Potential Piece of Yellowism" in black in the corner of the painting before quickly leaving room.

Umanets, co-creator of the Yellowism movement –which, according to an online manifesto, is "not art or anti-art" -- said he had done so in order to draw attention to what was going on in contemporary art, BBC News reveals.
London’s Tate Modern issued a brief statement : "Tate can confirm that at 15.25 this afternoon there was an incident at Tate Modern in which a visitor defaced one of Rothko's Seagram murals by applying a small area of black paint with a brush to the painting. The police are currently investigating the incident."

Umanets told The Guardian "I believe that if someone restores the 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 signed a urinal and called it art in 1917.
"I don't believe that what I have done is criminal. If the police are going to arrest me, then they are going to arrest me. I am OK with that," he went on, adding that he admired the Russian-American abstract painter’s work.
The Seagram murals were painted by Rothko in 1958 for Manhattan's Four Seasons restaurant, but were never installed.
Why would you deface a Rothko when there are so many perfectly defaceable Jeff Koons pieces.
