Original 1st printing 14&1/8 x 19&7/8" concert poster for the Steve Miller (Blues) Band appearing with Lee Michaels and the Peanut Butter Conspiracy at the Avalon Ballroom in San Francisco, CA from 2/10-11/1967.
Art by Victor Moscoso, image ("Sphinxdance") is # 47 in the Family Dog/Avalon series.
Thick flat vellum stock poster is in excellent (B+) condition; a series of VERY well-camouflaged thin bends/light creases hiding around the outer edges and a few within the image area, along with a touch of edge wear, a few stray tiny surface spots and a set of light tape pulls on the reverse, otherwise fine.
VERY sharp-looking example of the 1st printing Moscoso "Sphinxdance" poster.
