This trim art book showcases some of Keith Haring's most elusive art: his chalk on black paper drawings that were created on the walls of the New York City subways. From 1980 to 1985, Haring created more than 5,000 chalk drawings: he jumped out at a subway stop, found an empty wall panel, filled it with spontaneous art and boarded the next train, seeking another blank canvas. "The drawings are by necessity quick and simple," writes Haring. "This is not only for easy readability but also to avoid getting arrested." Most of this art is preserved only through photos taken at the time. Some show Haring creating them while subway passengers rush past. The collected art is vintage Haring: goofy, bold, political and accessible. --Kevin Howell, independent reviewer and marketing consultant
