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 mint/near mint to near mint (A/A- to A-) condition; perhaps there may be a tiny ding or two if you look REALLY closely, but overall it is an absolutely STUNNING example of this original '66 Dog flyer featuring Victor Moscoso's first-ever Grateful Dead image.
