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 from 9/23-24/1966 (*show was cancelled). 
 
 Art by Stanley Mouse and Alton Kelley, image is # 27 in the Family Dog/Avalon series.
 
 Thin flat stock flyer is in very good (B/B+) condition; there are tape residue spots and a couple of light surface pulls along the upper margin area and in the lower left/right margins/corners, along with another tiny pull in the right center margin, a tiny spot and a pair of razor-thin vertical stress bends in the lower right margin and a few soft bends/handling creases scattered around the outer margin area ,otherwise fine.
 
 VERY NICE-looking example of this always-popular 1966 Family Dog image.
