Original 1st printing (OP-2 in the Eric King guide, no "Double-H Press" credit) 14&1/8 x 20" 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.

Medium-thin flat index stock poster is in GORGEOUS mint/near mint to near mint (A/A- to A-) condition; a virtually flawless example of this classic 1967 Avalon poster with a nice large Mouse signature. BEAUTIFUL!
