Original 1st printing 8&1/2 x 11" concert flyer for Quicksilver Messenger Service appearing with Big Brother & the Holding Company (featuring Janis Joplin) and Country Joe & the Fish at the Avalon Ballroom in San Francisco, CA on 11/25-26/1966.
Art by Victor Moscoso, image is # 36 in the Family Dog/Avalon series. This is the WHITE stock version.
Thin flat stock flyer is in good to very good (B to B/B+) condition; a small 1/2" crescent-shaped wedge tear in the left center margin, a hint of moisture rippling, a few tiny pin-prick stains in the bottom right margin and an ultra-soft moisture stain in the upper right corner, otherwise fine.
Overall very decent-looking example of this late-'66 Family Dog flyer. Check out the original radio spot for the show!
