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 mint/near mint to near mint (A/A- to A-) condition; a touch of toning and a hint of corner wear, but overall it is a nice crisp/clean example of this pretty early 1967 Fillmore poster.
