Book excerpt: Disguised as a book of innocent postcards, Slingshot is a dangerous collection of Eric Drooker’s most notorious posters. Plastered on brick walls from New York to Berlin, tattooed on bodies from Kansas to Mexico City, Drooker’s graphics continue to infiltrate and inflame the body politic. Drooker is the author of two graphic novels, Flood! A Novel in Pictures (winner of the American Book Award), and Blood Song: A Silent Ballad. He collaborated with Beat poet Allen Ginsberg on the underground classic Illuminated Poems. His provocative art has appeared on countless posters and book covers, and his hard-edged graphics are a familiar sight on street corners throughout the world. Eric Drooker is a third-generation New Yorker, born and raised on Manhattan Island. His paintings are frequently seen on covers of the New Yorker and hang in various art collections throughout the U.S. and Europe.
