If Warhol is the king of Pop art, then Roy Lichtenstein is the movement’s crown prince. Now this prince’s unforgettable benday dots and swell comic attitude are celebrated in a new retrospective, complete with behind-the-scenes drawings, his greatest and most classic cartoony paintings of the ’60s and many under-known canvases that comment on the canon of 20th-century art history. Catch “Roy Lichtenstein: A Retrospective” organized by the Art Institute of Chicago traveling to Washington, D.C.’s National Gallery of Art (October 14 – January 13, 2013); London’s Tate Modern (February 21 – May 27, 2013); and Centre Pompidou in Paris (July 3 – November 4, 2013).
