Original 1st printing 10&3/4 x 17" concert poster for Frumious Bandersnatch appearing with Freedom Highway and Transatlantic Railroad at the Ark in Sausalito, CA on ?/1968 (no date on the poster).
Art by Dave Brown, medium-thin textured index stock is in good to very good (B to B/B+) condition; there are tack/staple holes and a bit of creasing/wear in the corners, a few stray handling dings, a piece of clear tape on "Band", a series of tiny pin-prick surface spots, a few semi-soft bends, a couple of small edge tears and light handling wear, otherwise fine.
MEGA-obscure Ark poster from 1968, this one hardly ever turns up.
