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 on 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; very light handling wear, a tiny surface smudge in the left of the ticket outlet area and a very soft 2" diagonal bend in the top right corner, otherwise fine. Sweet example of this very festive 1st printing 1966 GD/Moscoso Avalon image at a reasonable price.
