Yves Klein was a French painter considered to be a forefather of the Nouveau Realisme art movement. Klein is famous for creating Monochrome works, solid, single color paint on a canvas, devoid of any design or depictions. Some of Klein’s famous pieces include RE 46, which Yves Klein completed in 1960 and the 1962 work IKB 191. In 2006, RE 46 became among the top five highest grossing pieces sold by Christie’s, the Manhattan-based Auction House in the post World War II era. The Monochrome style was controversial to some, but Yves Klein maintained his reason for creating such work was to encourage those who viewed it to draw their own conclusions about what it was about, or the emotions it attempted to evoke.
