A prodigious purveyor of perverted art and the doyen of underground comix, Robert Dennis Crumb (“R. Crumb” in his signatures) has been illustrating the unhinged imagery lodged in his unconscious for six decades and counting. To his ongoing bewilderment, the controversial and formerly destitute artist’s drawings and cartoons now fetch top dollar at esteemed gallery exhibitions, such as David Zwirner’s recent Drawing for Print: Mind Fucks, Kultur Klashes, Pulp Fiction & Pulp Fact by the Illustrious R. Crumb. Before he was famous, though, Crumb endured all sorts of problems. Though he’d made a splash in 1968 with his Zap Comix series, which helped define the underground comix aesthetic, his early thirties were plagued by disastrous relationships, lawsuits, financial struggles, heavy LSD use, and copyright infringements (including an X-rated film made about his Fritz the Cat character without his permission). But things started looking up as Crumb approached his 40th birthday — thanks, in part, to Weirdo, an independent magazine he launched in 1981 following a flash of insight during a meditation session.
