rights movement. His work became popular and controversial. Warhol had this to say about Coca-Cola: In 1962, Warhol created his famous Marilyn series. The Flavor Marilyns were selected from a group of fourteen canvases in the sub-series, each measuring 20" x 16". Some of the canvases were named after various candy Life Savers flavors, including Cherry Marilyn, Lemon Marilyn, and Licorice Marilyn. The others are identified by their background colors. Warhol produced both comic and serious works; his subject could be a soup can or an electric chair. Warhol used the same techniques—silkscreens, reproduced serially, and often painted with bright colors—whether he painted celebrities, everyday objects, or images of suicide, car crashes, and disasters, as in the 1962–63 Death and Disaster series. In 1979, Warhol was commissioned to paint a BMW M1 Group 4 racing version for the fourth installment of the BMW Art Car project. He was initially asked to paint a BMW 320i in 1978, but the car model was changed and it didn't qualify for the race that year. Warhol was the first artist to paint directly onto the automobile himself instead of letting technicians transfer a scale-model design to the car. Reportedly, it took him only 23 minutes to paint the entire car. Racecar drivers Hervé Poulain, Manfred Winkelhock and Marcel Mignot drove the car at the 1979 24 Hours of Le Mans. Some of Warhol's work, as well as his own personality, has been described as being Keatonesque. Warhol has been described as playing dumb to the media. He sometimes refused to explain his work. He has suggested that all one needs to know about his work is "already there 'on the surface. His Rorschach inkblots are intended as pop comments on art and what art could be. His cow wallpaper (literally, wallpaper with a cow motif) and his oxidation paintings (canvases prepared with copper paint that was then oxidized with urine) are also noteworthy in this context. Equally noteworthy is the way these works—and their means of production—mirrored the atmosphere at Andy's New York "Factory". Biographer Bob Colacello provides some details on Andy's "piss paintings": Warhol's 1982 portrait of Basquiat, Jean-Michel Basquiat, is a silkscreen over an oxidized copper "piss painting." After many years of silkscreen, oxidation, photography, etc., Warhol returned to painting with a brush in hand. In 1983, Warhol began collaborating with Basquiat and Clemente. Warhol and Basquiat created a series of
