Graffiti is generally dismissed as a form of urban vandalism, but in the late 1970s art collectors and museums began to look on graffiti as a genre worthy of serious aesthetic consideration. This survey discusses the graffiti work of artists including Lee Quinones, Jenny Holzer and Kenny Scharf, and includes Henry Chalfant's meticulously photographed reproductions of the work. Richard Flood, Curator for the Walker Art Center and of this exhibition, offers his meditations on the complex aesthetic and sociological issues generated by graffiti.
