Original 1st printing 21&3/4 x 26&1/4" concert poster for the Grateful Dead appearing with the Sons of Champlin and Initial Shock at the Avalon Ballroom In San Francisco, CA from 1/24-26/1969.
Art by Rick Griffin, image ("Aoxoamoxoa") is featured in the Art of Rock book on page 109 (plate 2.24).
Medium glossy-coated index stock poster is in excellent (B+) condition; with the exception of a small 1&3/8" diagonal bend, a tiny pinch bend in the lower left corner and just the slightest whisper of surface wear (a stray fingerprint or two), this example is VERY crisp/clean overall with very strong colors.
An overall SUPERB-looking 1st printing example of the Griffin Aoxomoxoa Dead poster, one of the finest I have seen. Check out the 1/26 show (another great Charlie Miller transfer) HERE:
