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-) condition; just a couple of stray soft handling dings hiding within the image area and that's pretty much IT... a VERY sharp/clean example of this mid-'67 Fillmore image.
