R. Crumb is a comic artist and a founder of the underground comix movement of the 1960s. Among his creations are Fritz the Cat, Mr. Natural, and the Keep on Truckin’ dude(s). His album covers include the classic Cheap Thrills by Big Brother and the Holding Company.
Toyota offered Crumb $100,000 to use his Keep on Truckin’ work in their ad campaign but he turned them down. His work epitomizes a worldview that rejects materialism in favor of natural and spiritual values. He is a man with a keen eye for bullshit, as evidenced by this strip from 28 years ago.
