Original 1st printing 14&3/8 x 20" concert poster for Chicago blues legend James Cotton appearing with S.F. psych-folk band the Wildflower at the Matrix in San Francisco, CA, from 11/22-27/1966.
Art by Carol Behan/Fish Productions, medium-thick flat vellum stock poster is in very good (B/B+) condition; a few tiny staple holes (top left/right corners) a couple of very soft diagonal bends in the upper left corner, a few stray handling dings/tiny surface spots hiding within the image area and an odd blue-ballpoint pen doodle on the reverse, otherwise fine.
Neat-looking late-'66 Matrix poster, this example has also been HAND-SIGNED (in blue sharpie) by James Cotton himself!
