Original 1st printing 8&1/2 x 11" concert flyer for Big Brother & the Holding Company (featuring Janis Joplin)* appearing with Blue Cheer in a legal-aid benefit for the Hells Angels Motorcycle Club, held at California Hall in San Francisco, CA on 2/3/1967.
 
 Art by Allen "Gut" Terk, image is featured in the Art of Rock book on page 207 (plate 2.248). 

Thin flat stock flyer is in near mint (A-/B+) condition; really nothing more than a few ultra-light handling dings here and there and a tiny pin-prick scuff/spot on the reverse side, otherwise it is a VERY sharp example of this always-popular HAMC/Big Brother concert artifact.
