Original 1st printing 8&1/2 x 11" concert flyer for Quicksilver Messenger Service appearing along with the Sons of Champlin and Blackburn & Snow at the Avalon Ballroom in San Francisco, CA on 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 good to very good (B to B/B+) condition; about a 1" square area of pin-prick rust/age spots just below and around "Ticket Outlets" along with a few other ultra-tiny spots spread around the margins, a few light thin handling bends/soft creases here and there, a whisper of toning and a flattened horizontal center crease, otherwise fine.
One of Victor Moscoso's earliest Avalon images, overall a very nice-looking example.
