Official promoter-issued 1967 2nd printing 14 x 20" concert poster for Country Joe & the Fish appearing with Lee Michaels and Moby Grape at the Avalon Ballroom in San Francisco, CA from 12/30-31/1966.
 
 Art by Stanley Mouse (whom has also HAND-SIGNED the poster in black flair pen) and Alton Kelley, image is # 41 in the Family Dog/Avalon series.
 
 Medium flat index stock poster is in excellent (B+) condition; there are a couple of fairly well-camouflaged thin stress bends on the "D" of "Dec.", along with a few stray handling dings here and there, a tiny edge bump or two and that's pretty much it... a nice-looking ARTIST-SIGNED example of the FD 41 image.
