Original 1st printing 14 x 23&7/8" concert poster for Chicago blues legend Howlin' Wolf appearing with Big Brother & the Holding Company (featuring Janis Joplin) and the Harbinger Complex at the Fillmore Auditorium in San Francisco, CA from 4/21-23/1967.
Art by Wes Wilson, image is # 60 in the Bill Graham/Fillmore series.
Medium-thick flat index stock poster is in fantastic near mint (A-/B+) condition; a touch of edge toning and a hint of corner/edge wear (a couple of stray soft fingerprints around the outer edges and a tiny ding in the bottom margin), but overall it is a VERY nice-looking crisp/clean example of this early 1967 Fillmore poster.
