Original 1st printing 13&3/8 x 22&1/2" concert poster for Otis Rush & His Chicago Blues Band appearing with the Mothers of Invention (featuring Frank Zappa) and Morning Glory at the Fillmore Auditorium in San Francisco, CA from 3/3-5/1967.
 
 Art by Wes Wilson, image is # 53 in the Bill Graham/Fillmore series.
 
 Medium flat vellum stock poster is in very good (B/B+) condition; there are a few thin horizontal/diagonal creases with a couple of tiny roll bends/pressure creases and a tiny tear scattered along the top margin, along with a couple of thin diagonal corner-tip creases, a bit of minor handling wear and a couple of tiny stains on the reverse, otherwise fine.
 
A lightly-aged/gently-used example of this always-popular early-'67 Fillmore poster.
