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 near mint to excellent (A-/B+ to B+) condition; aside from a very soft diagonal bend in the lower left corner/margin, a couple of tiny corner tip bumps and a few nearly-invisible handling dings/fingerprints hiding within the image area, it is a FANTASTIC example of this fairly weird mid-1968 Fillmore image with a very trippy nautical-inspired design.
