John Van Hamersveld (*1941) ranks among the great illustrators of popular culture. His visual imagination helped shape the iconography of the '60s and '70s; he was among those who gave psychedelia an artistic vocabulary. In the ensuing decades he's applied his relentless creativity to everything from street art to corporate advertising. Among his creations are an official poster and 360-foot-long mural for the 1984 Los Angeles Olympic Games, illustrations for Esquire, Rolling Stone, Billboard, and branding and logos for Fatburger, Contempo Casuals, and Broadway Deli.
