Original 1st printing 8&1/2" square concert/event handbill, for "Whatever It Is", a three-day concert/symposium/"happening", held on the campus of San Francisco State College from 9/30-10/2/1966, conceived by Stewart Brand (Whole Earth Catalog) and the Associated Students of SFSC/Experimental College.

 Participants included: the Merry Pranksters (conducting one of the last Acid Test events, featuring the Grateful Dead), Mimi Farina, the Only Alternative and His Other Possibilities, Wildflower, Final Solution, Congress of Wonders, the Committee, San Francisco Mime Troupe and many more.

 Designer unknown/not credited, thin flat stock handbill is in near mint (A-) condition; there may be a soft handling ding hiding somewhere, but I can't really see anything- but just to be safe, I'll say it's just a hair below mint... a VERY clean example.
