Original 1st printing 8&1/2 x 11" concert flyer for Quicksilver Messenger Service appearing with the Great Society (featuring Grace Slick) at the Avalon Ballroom in San Francisco, CA on 9/9-10/1966.
 
 Art by Stanley Mouse and Alton Kelley with a photo by Edward S. Curtis, image ("Bull Bear") is # 25 in the Family Dog/Avalon series.
 
 Thin flat stock flyer is in excellent (B+) condition; aside from a touch of handling wear and a nearly-invisible set of tape shadows on the reverse side, it is a VERY sharp example of this early Family Dog flyer.
