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 on 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 very good (B/B+) condition; a couple of soft smudges in the top center margin, a pair of soft horizontal bends and light handling dings/tiny stress bends in the upper/lower right margins and a pair of archival tape pieces on the reverse (top margin), otherwise fine.

 An very decent-looking example of this perennially popular Victor Moscoso image.
