Official promoter-issued 1967 3rd printing 14 x 20" concert poster for the Grateful Dead appearing with Oxford Circle at the Avalon Ballroom in San Francisco, CA from 9/16-17/1966.
Art by Stanley Mouse and Alton Kelley (central image borrowed from Edmund Sullivan), image ("Skeleton and Roses") is # 26 in the Family Dog/Avalon series.
Medium flat index stock poster is in BEAUTIFUL near mint (A- to A-/B+) condition; just a couple of subtle handling dings and the slightest whisper of surface wear, otherwise this example is just about as/crisp and bright as you can ask for.
An overall GORGEOUS 3rd-printing example of the classic "Skeleton and Roses" image that won't break the bank. Have a listen to the show (PRIMAL '66 Dead) HERE:
