Original 1st printing (OP-2 flat/matte stock) 14 x 20" concert poster for Country Joe & the Fish appearing along with the Sparrow (proto-Steppenwolf) and Kaleidoscope (featuring David Lindley) at the Avalon Ballroom in San Francisco, CA on 2/3-4/1967. Art by Victor Moscoso, image ("Dance of the Five Moons") is # 46 in the Family Dog/Avalon series. Medium flat index stock poster is in very good to excellent (B/B+ to B+) condition; a couple of scattered edge/corner bumps and pinch bends, a hint of toning, a stray pinch ding or two and slightly worn bottom left/right right corner tips, otherwise fine. An overall very nice-looking example of this early 1967 Avalon poster.
