Original 1st printing (OP-2 in the Eric King guide, no "Double-H Press" credit) 14&1/8 x 19&7/8" concert poster for Moby Grape appearing with the Sparrow and the Charlatans at the Avalon Ballroom in San Francisco, CA from 1/13-14/1967. Poster also mentions the 1/14/1967 Gathering of the Tribes at Golden Gate Park.
Art by Stanley Mouse and Alton Kelley, image is # 43 in the Family Dog/Avalon series.
Medium-thin flat index stock poster is in VERY sharp mint near mint to near mint (A/A- to A- ) condition; there are a couple of tiny smudges on the reverse, but the entire front of the poster is in SPARKLING shape... a GORGEOUS example of this now 50-year old Mouse/Kelley image from the Avalon.
