Official promoter-issued (1966) 2nd printing 14&1/4 x 19&7/8" concert poster for the Grateful Dead appearing with the Oxford Circle at the Avalon Ballroom in San Francisco, CA from 9/16-17/1966.
Art by Alton Kelley and Stanley Mouse (central image by Edmund Sullivan), image ("Skeleton & Roses") is # 26 in the Family Dog/Avalon series.
Medium-thick flat vellum stock poster is in near mint to excellent (A-/B+ to B+) condition; aside from a couple of tiny hairline bends in the lower left corner tip, a hint of edge wear, a nearly-invisible soft pinch ding or two hiding within the image area and just the slightest amount of toning, it is an absolutely STUNNING example of the 2nd printing FD 26 poster.
