Original 1st printing 5&3/8 x 7&5/8" concert handbill for Big Brother & the Holding Company (featuring Janis Joplin -her debut performances with the band) appearing with Quicksilver Messenger Service at the Avalon Ballroom in San Francisco, CA from 6/24-25/1966.
Art by Stanley Mouse (who has also SIGNED the piece in pencil) and Alton Kelley, image ("Zig-Zag") is # 14 in the Family Dog/Avalon series, this is the gold-logo version (OHB-A in the Eric King guide).
Thin flat stock handbill is in STUNNING near mint (A-) condition; aside from a pair of tiny bends in the lower left/right corner tips and the slightest whisper of handling, this is probably one of the best-looking examples I have ever come across.
An absolutely GORGEOUS ARTIST-SIGNED example of the VERY early Avalon handbill.
