Original 1st printing 13&5/8 x 20&3/4" concert poster for the Blues Project (featuring Al Kooper and Steve Katz (Blood, Sweat & Tears) appearing with Frank Zappa and the Mothers of Invention and the Canned Heat Blues Band at the Fillmore Auditorium in San Francisco, CA from 2/17-19/1967.
Art by Wes Wilson, image is # 50 in the Bill Graham/Fillmore series.
Medium-thick flat vellum stock poster is in absolutely fantastic near mint (A-/B+) condition; just a couple of ultra-thin horizontal hairline bends running along the top left margin, a tiny pressure bend/split in the lower left corner tip and a whisper of handling, otherwise fine.
An overall GORGEOUS example of this original early-'67 Wes Wilson-designed Fillmore poster.
