Official Sparta Graphics-issued 2nd printing (red lettering) 17 x 22" concert poster for Jefferson Airplane appearing with William Penn & His Pals and the E-Types at the San Jose Civic Auditorium on 6/4/1966.

 Artist/designer unknown/not credited, image is featured in the Art of Rock book on page 286 (plate 3.99). 

 Medium-thick flat vellum stock poster is in excellent (B+) condition; aside from a tiny pressure crease/nip tear in the lower left margin, a touch of handling wear, a few small dings/light pinch bends scattered around the outer margin area and a tiny corner-tip bump or two, it is a fantastic-looking period example of this whimsical Jefferson Airplane poster from San Jose.
