Original 1st printing 28&1/4 x 22" 1967 promotional poster for San Francisco, CA-based free-form FM rock radio station KMPX-FM.
 
  Art by Stanley Mouse (whom has also HAND-SIGNED the poster in gold ink- see close-up) with Alton Kelley, image (green background version) is featured in the Art of Rock book on page 210 (plate 2.259). This is the more-common brown-background version.
 
 Medium-thick flat index stock poster is in very good to excellent (B/B+ to B+) condition; there are a series of semi-pronounced creases/bends along the upper right margin (each about 2-3" long by 1" deep), along with a few soft handling dings/fingerprint smudges here and there, a tiny nip tear in the top center margin and a couple of VERY minor edge/corner-tip dings, otherwise fine. An overall great-looking Mouse-SIGNED example of the brown '67 KMPX poster.
