Roy Lichtenstein “Nude in Mirror” / knife

(In 2005, a woman visiting a Lichtenstein retrospective at Austria’s Kunsthaus Bregenz suddenly pulled a knife from her handbag and repeatedly stabbed this work, leaving four 12-inch-long slashes in the canvas. Upon her arrest, police found that her purse also contained a screwdriver and a can of red spray paint, which she said she hadn’t had time to use. She said she attacked the work because she thought it was a forgery.)
