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 good (B) condition; there is a fairly decent-sized moisture/coffee stain on the reverse that bleeds through the paper into the right center margin area (about 5"), along with a small round droplet stain in the upper right quadrant and a few tiny stress creases along the lower left margin/corner, a trace of moisture rippling in the bottom right corner tip, a soft bend in the upper margin and a stray soft handling ding or two hiding within the image area, otherwise fine.

 The conditional issues on this one aren't actually all that bad, it still looks pretty good overall.
