The rock n’ roll legend Graham Nash, singer and songwriter with the 1970s supergroup group Crosby, Stills & Nash, is offering several pieces by Robert Crumb, the countercultural cartoonist, at auction next month. Nash has consigned various Crumb classics to Heritage Auctions’ Comic Auctions in Dallas (10-12 August) including Zap Comix #1, cover original art dating from 1967 (est $100,000). The cartoonist himself features in The People’s Comics (1972; est $50,000), depicting his various escapades including working on a farm for bourgeois intellectuals and artists. After school in Delaware, Crumb found work in Cleveland, Ohio, illustrating for the American Greetings card company, but his comics flourished after he moved to San Francisco in 1967. There, characters such as the mystic Mr Natural were born, and Crumb became a key figure in the counterculture and a fixture in Zap Comix, fashioning racy images that raised the eyebrows of conservatives and feminists alike.
