Original 1st printing 16&7/8 x 22&7/8" concert poster for Jefferson Airplane appearing at the Earl Warren Showgrounds in Santa Barbara, CA on 10/7/1967.
 

 Art by R. Tolmach, image is featured in the Art of Rock book on page 268 (plate 3.45) and is part of the Jim Salzer Presents series. 
 
 Medium-thin flat vellum stock poster is in near mint to excellent (A-/B+ to B+) condition; aside from a couple of ultra-tiny pressure dings scattered around the outer margin area, a tiny nip out of the bottom left corner tip and a stray soft handling ding or two hiding within the image area, it is a SUPERB example of this evocative J.A. poster from the Salzer series; check out a great informative list of 1960's-era shows (including this one) held at the Earl Warren Showgrounds HERE:
