Poll: Is two years in prison the right punishment for man who defaced Rothko painting? Wlodzimierz Umaniec made headlines earlier this year by scrawling his pseudonym - Vladimir Umanets - in the bottom right corner of Rothko's Black on Maroon, which has an estimated value of between £5m and £9m. He admitted causing criminal damage in excess of £5,000 but defended his actions by saying the grafitti was part of the 'Yellowist' art movement, which he co-founded, and constituted a "gift to the nation." Judge Roger Chapel described Umaniec as "plainly an intelligent man" - but nevertheless sentenced him to two years. Does the punishment fit the crime?
