Original 1st printing 13&7/8 x 19&3/4" concert poster for the (Amazing) Charlatans with the Mystery Trend, Slaxon, "the Slight-of Head Magician" and Wanda & Her Birds (a trained bird act) at California Hall in San Francisco, CA on 4/16/1967. Art by Jack DeGovia, image is featured in the Art of Rock book on page 178 (plate 2.159). Medium flat index stock poster has been professionally restored to excellent (B+) condition; several staple/pin holes have been filled, along with a small 1&1/2" area of paper fill in the lower left margin, next to "Joint Project", a flattened 4" diagonal bend in the top right corner, a pair of tiny brown tape residue marks in the top left/right corners and a couple of stray tiny surface marks, otherwise a fine-looking example of this totally weird-looking Cal Hall poster from the AOR.
