The original painting used to make the "world's most popular art print" auctioned for $1.5 million at Bonham's in London on March 20, 2013. The charcoal drawing on a brown canvas is called "Chinese Girl." The artist added a green-blue color to the face and bright yellow to her tunic. It set a record for a work by South African artist Vladimir Tretchikoff (1913-2006). Many considered his work to be "kitsch."
