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 Train at 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 very good to excellent (B/B+ to B+) condition; there are a pair of tiny wedges out of the upper left margin, along with staple holes in the upper left corner and in the top/bottom center margins, a soft vertical bend in the left margin, a few tiny crinkles and a minuscule nip along the top margin, a stray handling ding/thin stress bend or two hiding within the image area and a bit of minor red ink streaking on the reverse side, otherwise it is a FANTASTIC example of this iconic late-'66 Avalon flyer.
