Original 1st printing 8&1/2 x 11" concert flyer 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.
Thin flat stock flyer is in VERY sharp near mint (A- to A-/B+) condition; aside from a few ultra-soft handling dings scattered around the image area and a tiny edge ding or two, it is essentially as clean as they come.
A SUPERB example of this perennially popular late-'66 Grateful Dead image.
