Original 1st printing 14 x 17" concert poster for Moby Grape with A.B. Skhy and Gale Garnett and the Gentle Reign and Group Therapy at the Avalon Ballroom in San Francisco, CA on 3/7-9/1969. Art by Greg Irons, image is featured in the Art of Rock on page 111 (plate 2.29). Medium-thin glossy stock poster is in spectacular near mint (A-/B+) condition; aside from a stray surface ding or two, light handling wear in the upper right corner and a couple of tiny edge nicks, otherwise an absolutely GORGEOUS-looking example of this classic Greg Irons image with really bright vivid colors.
