Original 1st printing 8&1/2 x 11" concert/event flyer for the 1/14/1967 Gathering of the Tribes/Human Be-In, held at the Polo Grounds in San Francisco's Golden Gate Park. This version lists appearances by counterculture heroes Lenore Kandel, Timothy Leary, Michael McClure, Allen Ginsberg, Gary Snyder, Richard Alpert, Jerry Rubin, Dick Gregory, Lawrence Ferlinghetti and "all SF rock bands" (which included Jefferson Airplane, Quicksilver Messenger Service, the Charlatans, the Grateful Dead and more).
Art by Rick Griffin, image is featured in the Art of Rock on page 197 (plate 2.216).
Thin flat textured stock flyer is in absolutely fantastic mint/near mint to near mint (A/A- to A-) condition; an essentially unbeatable crisp/clean example of this classic Rick Griffin flyer from an epochal event in counterculture history. KILLER!!!!
