Original 1st printing 8&1/2 x 11" concert flyer for Quicksilver Messenger Service appearing with the Sons of Champlin and Blackburn and 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 very good to excellent (B/B+ to B+) condition; there are a couple of semi-soft diagonal bends in the upper left margin, along with a few other VERY subtle/soft bends hiding within the image area, a few light handling creases here and there, a tiny sliver of black ink in the right border and a couple of slightly soft corner tips, otherwise fine.

 Overall, a very nice-looking example of this semi-early Family Dog flyer.
