Original 1st printing 14&1/8 x 20" concert poster for the Chambers Brothers appearing at the Matrix in San Francisco, CA from 3/28-4/6/1967.

 Art by Victor Moscoso, image is # 12 in the Neon Rose series (NR-12-OP-1) and is featured in the Art of Rock on page 270 (plate 2.138).

 Medium flat index poster is in very good (B/B+) condition; there is a small 1&1/2" diagonal bend in the bottom left corner tip, along with a series of thin surface scratches and tiny pin-prick surface spots hiding within the image area, a thin diagonal bend in the upper left margin and a few additional tiny bends scattered around the outer margin area, otherwise fine.

 Very decent-looking example of this always-popular poster from the Neon Rose series.
