Original 1st printing 14&1/4 x 19&3/4" concert poster for the Grateful Dead appearing with Moby Grape and the Steve Miller Blues Band at the Avalon Ballroom in San Francisco, CA from 12/23-24/1966.

 Art by Victor Moscoso, image is # 40 in the Family Dog/Avalon series. 

 Medium-thick vellum stock poster is in near mint to excellent (A-/B+ to B+) condition; aside from a touch of handling wear and a few tiny pin-prick age spots and soft pinch creases scattered around the outer margin area, this example is just about as sharp as they come- a BEAUTIFUL specimen!
