Original 1st printing 6&1/2 x 9&3/8" concert handbill for the Paul Butterfield Blues Band (featuring Mike Bloomfield and Elvin Bishop) appearing with Jefferson Airplane at the Fillmore Auditorium in San Francisco, CA on 4/15 and 4/17/1966 and at Harmon Gymnasium on the campus of U.C. Berkeley on 4/16/1966. 

 Art by Wes Wilson, image ("Blues-Rock Bash") is # 3 in the Bill Graham/Fillmore series.

 Thin flat stock handbill is in very good to excellent (B/B+ to B+) condition; the piece was removed from a scrapbook, so there is a bit of light contact paper glue residue on the reverse side, along with a tiny semi-erased pencil shadow in the lower right margin and a couple of ULTRA-tiny pin-prick surface spots scattered around the top center margin, otherwise it is a VERY sharp example of this early Bill Graham handbill.
