Original 1st printing 14 x 20" concert poster for Jefferson Airplane appearing with the Grateful Dead at the Carousel Ballroom in San Francisco, CA from 3/15-17/1968.
Art by Alton Kelley, image ("Sore Thumb") is featured in the Art of Rock on page 182 (plate 2.172).
Medium flat index stock poster as been professionally restored to very good/excellent (B/B+ to B+) condition; sets of staple holes in all four corners have been filled, there are a couple of tiny slight stains at about 12:00 in the white border, plus a few scattered handling dings and a couple of minor surface scrapes here and there, otherwise fine- it presents itself quite nicely.
An overall great-looking example of this classic Dead/Airplane/Kelley/AOR image. Listen to the 3/16 Dead set HERE:
