Original 1st printing 13&1/2 x 23&1/2" concert poster for Jefferson Airplane, the Paul Butterfield Blues Band and Big Mama Thornton appearing together at the Fillmore Auditorium in San Francisco, CA from 10/14-16/1966.
 
 Art by Wes Wilson, image is # 31 in the Bill Graham/Fillmore series.
 
 Medium-thin flat vellum stock poster is in very good (B/B+) condition; there are pin/staple holes in all four corners and a few scattered around the outer margin area, with a bit of toning/discoloration towards the bottom margin, a few light handling dings and tiny pin-prick spots here and there, otherwise fine.

 VERY nice-looking 1st printing example of this semi-early (late-'66) Fillmore poster.
