Original 1st printing 8&1/2 x 11" concert flyer for the Jim Kweskin Jug Band (with Maria Muldaur) appearing with Big Brother & the Holding Company (featuring Janis Joplin) and Electric Trainat the Avalon Ballroom in San Francisco, CA from 10/7-8/1966.
 
 Art by Stanley Mouse and Alton Kelley, image ("Girl With Green Hair") is # 29 in the Family Dog/Avalon series. (*OHB-A in the Eric King guide)
 
 Thin flat stock flyer is in excellent (B+) condition; just a few soft bends and a couple of tiny pin-prick spots scattered around the outer border area, a trace of handling and a couple of tiny edge dings, otherwise it is a VERY sharp/clean example of this perennially popular Mouse/Kelley Avalon flyer.
