Original 1st printing 18&5/8" diameter round concert poster for Jefferson Airplane appearing with Buffalo Springfield (*canceled/replaced by Fever Tree) and Canned Heat at the Kaleidoscope in Los Angeles, CA from 4/22-23/1968.
Art by Dahlgren, image is featured in the Art of Rock book on page 280 (plate 3.79) and is # 4(A) in the Kaleidoscope series.
Medium-thin flat glossy stock poster is in absolutely fantastic near mint (A- to A-/B+) condition; only a few scattered handling/pinch dings and few nearly-invisible soft age spots around the outer edges, otherwise fine.
Great-looking original 1st printing Kaleidoscope poster featuring a great design and an unbeatable lineup; check out this great informative list of shows (including this one) held at the Kaleidoscope in 1968:
