Original 1st printing 14&1/8 x 20" concert poster for soul-psych legends the Chambers Brothers appearing at the Matrix in San Francisco, CA from 3/28-30/1967 and again from 4/4-5/1967.

 Art by Victor Moscoso, image is # 12 in the Neon Rose series and is featured in the Art of Rock book on page 170 (plate 2.128).

 Medium flat index stock poster is in BEAUTIFUL near mint (A- to A-/B+) condition; only a couple of ultra-tiny pinch bends in the upper left corner and the slightest whisper of surface wear, otherwise it is an ULTRA-crisp example of this hugely popular Victor Moscoso image.
