Original 1st printing 14 x 20" concert poster for Berkeley psych-rock heroes Country Joe & the Fish appearing with Fantastic Sensations on 2/16/1967, with Painted Ship on 2/17/1967 and with the United Empire Loyalists on 2/18/1967, all at the Afterthought in Vancouver, British Columbia, Canada.

 Art by Bob Masse, medium-thick flat index stock poster is in near mint (A-/B+) condition; only one or two tiny edge dings and a couple of pin-prick surface chips in the upper right margin, otherwise it is an absolutely gorgeous example of this oddball 1967 Bob Masse poster from one of Vancouver's earliest psychedelic hot spots.
