American pop artist Roy Lichtenstein created Masterpiece in 1962. The boldly composed painting features Brad, a hero who Lichtenstein incorporated into a variety of his pieces, and was printed using the Ben Day process – a type of illustration that's made up of dots and textures.
Masterpiece was part of Lichtenstein's first exhibition in Los Angeles in 1963, and its caption is seen as a tongue-in-cheek comment about the artist's own career. The artwork belonged to the American art collector Agnes Gund for years, but in January 2017 she sold it to hedge fund manager Steve Cohen for $165 million. That's $207 million (£167m) today.
