Original 1st printing 8&1/2 x 11" concert flyer for Big Brother & the Holding Company (featuring Janis Joplin) appearing with Quicksilver Messenger Service and Country Joe & the Fish at the Avalon Ballroom in San Francisco, CA from 11/25-26/1966.

Art by Victor Moscoso, image is # 36 in the Family Dog/Avalon series.

 Thin flat stock flyer is in near mint (A- to A-/B+) condition; aside from a few soft handling dings here and there and a hint of scrapbook paper residue on the reverse side, it is a VERY sharp/clean example of this always-popular late-'66 Avalon flyer with a sweet Moscoso design.
