Original 1st printing 16&1/8 x 23&1/4" concert poster for the Dinosaurs (featuring John Cipollina (Quicksilver) Joey Covington (Jefferson Airplane), Peter Albin (Big Brother & the Holding Company) and Barry Melton (Country Joe & the Fish) appearing at the Starry Night in Portland, OR on 7/14/1983 and at the Paramount in Seattle, WA on 7/16/1983.
 
 Art by Alton Kelley, medium-thick flat index front/glossy reverse poster is in good/decent (B to B/B-) condition; there are a series of fairly pronounced horizontal stress bends stretching across the image area, along with a few light handling dings, a thin vertical/diagonal stress crease or two hiding within the image area, a small spot/stain in the lower right corner and a bit of scuffing on the reverse side, otherwise OK.

Conditional issues aside, this is one of the harder-to-find Dinosaurs posters- I haven't had one of these pass through in YEARS.
