Original 1st printing 14&1/8 x 20" concert poster for the Jim Kweskin Jug Band appearing with Big Brother & the Holding Company (featuring Janis Joplin) and the Electric Train at the Avalon Ballroom in San Francisco, CA from 10/7-8/1966.
Art by Stanley Mouse and Alton Kelley, image is # 29 in the Family Dog/Avalon series.
Medium-thick flat vellum stock poster is in very good (B/B+) condition; there are pin holes in each corner, a 1/2" tear in the top center margin, a hint of toning, a 1/8" tear in the bottom center margin, a soft discoloration in the upper right margin, a few stray handling dings and a set of tape pulls on the reverse, otherwise fine.
An overall fine-looking, gently aged example of this early Mouse/Kelley classic from the Avalon.
