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 near mint to excellent (A-/B+ to B+) condition; aside from a tiny edge nip in the lower left margin, a whisper of handling wear and a slightly off-register pass of red ink, it is a VERY sharp example of Moscoso's always-popular "Hippie Santa" Grateful Dead flyer from the Avalon.
