Original 1st printing 8&1/2 x 11" concert flyer for Quicksilver Messenger Service appearing with the Sons of Champlin and Blackburn & Snow at the Avalon Ballroom in San Francisco, CA from 10/28-29/1966.
Art by Victor Moscoso, image ("Chicken on a Unicycle") is # 32 in the Family Dog/Avalon series.
Thin flat stock flyer is in excellent (B+) condition; aside from a light amount of surface wear (a few tiny pin-prick smudges), a couple of tiny corner-tip creases, a few soft handling dings/thin stress bends hiding within the image area, a tiny bit of moisture stress in the lower left corner/margin and a nearly-invisible set of light pulls on the reverse, it is a SUPERB example of one of Victor Moscoso's earliest Avalon images.
