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 very good (B/B+) condition; there are a series of VERY well-camouflaged thin horizontal bends/creases hiding around the outer edges and within the image area (mostly along the top margin), along with a set of tack holes (bottom left, upper/lower right corners), a large nail hole and 1&1/2" diagonal bend in the top left corner, a touch of edge wear, light toning, a few stray tiny pin-prick surface spots and a couple of light tape pulls on the reverse, otherwise fine.
Nice-looking gently-aged example of the 1st printing Moscoso "Sphinxdance" poster.
