Original 1st printing 14&1/8 x 20" concert poster for Chicago blues legend Howlin' Wolf appearing with Big Brother & the Holding Company (featuring Janis Joplin) at the Avalon Ballroom in San Francisco, CA from 9/23-24/1966 (*show was canceled). 

 

 Art by (and SIGNED in pencil by) Stanley Mouse (only) & Alton Kelley, image is # 27 in the Family Dog/Avalon series.

 

 Medium-thick flat vellum stock poster is in very good to excellent (B/B+ to B+) condition; a few soft handling bends scattered around the edges, a set of tiny staple holes in the upper/lower left/right margins, a subtle horizontal wave to the paper, a couple of soft pin-prick stains in the upper left/right margins and a whisper of edge/corner wear, otherwise fine.

 

 A SUPERB-looking original MOUSE-SIGNED example of this classic 1966 Family Dog image.
