Original 1st printing 21&3/4 x 26&1/4" concert poster for the Grateful Dead with the Sons of Champlin and Initial Shock at the Avalon Ballroom In San Francisco, CA on 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 absolutely stunning near mint (A-) condition; aside from a couple of tiny nicks in the bottom margin, a whisper of handling and a stray surface scratch or two, this is just as crisp/sharp an example of this poster as can be. A GORGEOUS-looking specimen of one of the top psychedelic poster images of all time, a must-have for the serious collector. Check out the 1/26 show (another Charlie Miller transfer) HERE:
