Original 1st printing 14 x 23&3/4" concert poster for 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 flat index stock poster in near mint (A-/B+) condition; aside from a tiny moisture ripple in the upper right margin/corner and a nearly-invisible soft pinch ding or two hiding within the image area, it is a FANTASTIC-looking nearly-clean example of this sweet mid-'67 Wes Wilson image from the Fillmore.
