Original 1st printing 14 x 21&1/8" concert poster for Country Joe & the Fish appearing with the Incredible String Band and Albert Collins at the Fillmore Auditorium in San Francisco, CA from 5/16-18/1968.
Art by Wilfred Weisser, image is # 120 in the Bill Graham/Fillmore series.
Medium-thick flat index stock poster is in absolutely GORGEOUS mint/near mint (A/A- to A-) condition; a spectacularly clean/crisp example of this mid-1968 Fillmore image with a decidedly psychedelic nauticall-inspired design.
