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 very good (B/B+) condition; there is a bit of creasing and a few tiny edge tears/splits scattered along the top margin, along with a thin diagonal 1" bend in the lower right corner, a series of light handling dings and well-camouflaged creases here and there and a flattened horizontal/diagonal center crease, otherwise fine.

 Very nice-looking gently-used example of this perennially popular HAMC item from an early-'67 benefit.
