Original 1st printing 8&1/2 x 11" concert flyer for Chicago blues legend Howlin' Wolf appearing with Big Brother & the Holding Company (featuring Janis Joplin) at the Avalon Ballroom in San Francisco, CA on 9/23-24/1966 (*show canceled).
Art by Stanley Mouse & Alton Kelley, image is # 27 in the Family Dog/Avalon series.
Thin flat stock flyer is in near mint to excellent (A-/B+ to B+) condition; aside from a tiny bit of moisture wear (a few tiny stress bends) in the lower left corner, a soft handling ding or two hiding within the image area, a tiny smudge and pin-prick spot in the right center margin and a touch of light waviness to the paper, otherwise fine.
An overall FANTASTIC example of this classic Mouse/Kelley flyer from the Avalon.
