Original 1st printing 8&/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 excellent (B+) condition; aside from a minuscule edge nip and a couple of ultra-tiny creases in the lower right margin, a nearly-invisible stress bend hiding in the lower right quadrant and a few semi-soft pinch dings scattered around the outer margin area, it is an absolutely FANTASTIC example of Moscoso's always-popular "Hippie Santa" Grateful Dead flyer from the Avalon.
