Original 1st printing 13&1/8 x 19&5/8" concert/event poster for "Joyful Alternative- Peace Poets Dance" featuring music by Country Joe & the Fish and Serpent Power, along with poettry readings by a number of SF poets (Richard Brautigan, Lenore Kandel, Charles Upton, Kenneth Patchen (who also did the little cat drawing in the bottom right corner), David Metzler (also appearing with Serpent Power) and more at California Hall in San Francisco on 4/13/1967. Design by John H. Myers (and the aforementioned Kenneth Patchen), medium flat vellum stock poster is in spectacular near mint (A-) condition; just the tiniest pair of nearly-invisible stress bends above "Alternative" and a tiny ding in the top edge, otherwise an absolutely gorgeous example of this semi-obscure San Francisco event poster with a great psychedelic design.
