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 to excellent (B/B+ to B+) condition; there are a series of VERY well-camouflaged tiny stress creases/thin bends hiding within the image area that are mostly visible from the reverse side, otherwise it is a GORGEOUS example of this perennially popular Neon Rose image.
