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 good to excellent (B/B+ to B+B+) condition; there are a couple of slight pressure crease indentations along the left margin (each about 1" long, likely from a three-ring binder), along with a couple of tiny thin vertical hairline bends and a couple of tiny edge nips in the lower right margin, a hint of handling wear and a VERY soft diagonal bend (about 5-6" long, you have to tilt the piece slightly in order to see it clearly) in the lower left margin/corner, otherwise it is a fine-looking example of Moscoso's very first Grateful Dead image.
