Carol Vogel of the New York Times reports that the man who defaced part of a Rothko mural at the Tate Modern in London earlier this year was sentenced to two years in jail. Twenty-six-year-old Wlodzimierz Umanets tagged the 1958 work, Black on Maroon, with the phrase A POTENTIAL PIECE OF YELLOWISM, after his own artistic movement “Yellowism.” He plead guilty to criminal damage in October of this year. The original value of the Rothko is estimated to be between eight and fourteen million dollars.
