Original 1st printing 25 x 9&3/8" concert poster for the Sons of Champlin appearing with Frumious Bandersnatch, Morning Glory and Initial Shock at the Western Front in San Francisco, CA from 10/6-7/1967.
Art by John Thompson, medium-thin flat index stock poster is in excellent (B+) condition; just a few stray handling dings scattered around the image area/margins and a couple of tiny corner creases, otherwise fine.
GREAT-looking old hippie poster from this semi-obscure (and VERY short-lived) San Francisco venue.
