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 (B/B+) condition; there is a thin semi-flattened vertical bend going through the center of the handbill, along with a few tiny creases hiding within the image area, a couple of loose pin-prick spots here and there and a soft bend or two lurking around the outer margin area, otherwise it is a very decent-looking example of this fairly early Fillmore handbill.
