Original 1st printing 13&5/8 x 23&1/4" concert poster for Jefferson Airplane appearing with Quicksilver Messenger Service and Dino Valenti at the Fillmore Auditorium in San Francisco, CA from 2/3-5/1967 (also mentions the 2/5 Strike Benefit at the Fillmore with the above lineup plus Country Joe & the Fish).
Art by Wes Wilson, image is # 48 in the Bill Graham/Fillmore series (OP-3 in the Eric King guide).
Medium flat vellum stock poster is in GORGEOUS near mint (A- to A-/B+) condition; only a couple of tiny edge/corner bumps/soft bends (top left/right, bottom left corners) and a couple of thin horizontal bends along the edge of the bottom margin, otherwise it's an absolutely STUNNING example of this early 1967 Fillmore poster with an awesome all-San Francisco lineup.
