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 good/decent (B/B-) condition; there are a pair of small wedges out of the top right corner tip/lower right margin, along with a couple of light surface pulls in the lower left/right corners (tape removal), a tiny sliver out of the lower left margin, a few light creases and a tiny nip tear or two lurking around the outer margins, a small 1/2" sliver out of the lower right margin/edge, a few tiny handing dings/pin-prick spots here and there and a trace of toning, otherwise fine.

 A used, but still presentable example of this oft-requested Mouse/Kelley-designed Avalon flyer.
