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 on 6/24-25/1966. Art by Stanley Mouse 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 excellent to near mint (B+ to B+/A-) condition; aside from a pair of tiny 1" bends in the bottom right corner and a whisper of handling, this is probably one of the sharpest examples I've ever come across. GORGEOUS early Avalon handbill.
