Bridging the gap between the art world and the street, Keith Haring rose to prominence in the early 1980s with his graffiti drawings made in the subways and on the sidewalks of New York City. Combining the appeal of cartoons with the raw energy of Art Brut artists like Jean DuBuffet, Haring developed a distinct pop-graffiti aesthetic centered on fluid, bold outlines against a dense, rhythmic overspread of imagery like that of babies, barking dogs, flying saucers, hearts, and Mickey Mouse. In his subway drawings and murals, Haring explored themes of exploitation, subjugation, drug abuse, and rising fears of nuclear holocaust, which became increasingly apocalyptic after his AIDS diagnosis. Alongside Jean-Michel Basquiat, Kenny Scharf, and Jenny Holzer, Haring is regarded as a leading figure in New York East Village Art scene in the 1970s and '80s.
