Original 1st printing 17 x 13" concert poster for the Dinosaurs (featuring John Cipollina (Quicksilver Messenger Service), Robert Hunter (Grateful Dead), Spencer Dryden (Jefferson Airplane), Peter Albin (Big Brother & the Holding Company) and Barry Melton (Country Joe & the Fish) appearing with Wettunes at the Corte Madera (CA) Recreation Center on 12/17/1983. (*Artista Christmas Party)

 Art by (and SIGNED in silver pen by) Alton Kelley, medium glossy-coated index stock poster is in very good to excellent (B/B+ to B+) condition; aside from a relatively minor amount of surface wear (a few stray fingerprints/light smudges/pin-prick spots here and there) and a loose edge/handling ding or two, otherwise it is a SUPERB-looking ARTIST-SIGNED example of this early-'80's Dinosaurs poster from Northern California.
