Original 1st printing 13&1/8 x 19&1/8" 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 and Alton Kelley, image is # 41 in the Family Dog/Avalon series
Medium-thick flat vellum stock poster is in very good (B/B+) condition; tack/pin holes (all four corners, left/right center margins) with a few tiny rust spots and ultra-tiny pulls, a soft surface smudge or two, a small edge bump/ding in the upper right edge, a hint of handling, a whisper of toning and a couple of really minor edge dings, otherwise fine.
An overall fine-looking example of this classic late-'66 Mouse/Kelley Avalon image that would look great in a nice old wood frame.
