Original 1st printing 13&3/4 x 20&1/4" concert poster for San Francisco supergroup 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 at the Golden Bear in Huntington Beach, CA on 3/24/1983 and at the Country Club in Reseda, CA on 3/25/1983.
 
 Art by Alton Kelley, image is # 6 in the Dinosaurs series.
 
 Medium-thick flat index (glossy reverse) stock poster is in near mint to excellent (A-/B+ to B+) condition; there a couple of light handling creases in the left center/upper right margins, along with a tiny pressure crease in the right center margin, otherwise it is a great-looking example of this Kelley Dinosaurs poster from Southern California.
 
 As an added bonus, this one has also been HAND-SIGNED (in pencil) by Cipollina, Hunter, Melton, Albin and Dryden. INCREDIBLE set of 1960's San Francisco musician signatures on one poster!
