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 tack holes (all four corners), along with a couple of semi-soft bends in the lower right corner, a series of tiny edge dings scattered around the outer margin area, a small vertical stress bend/crease in the lower left margin, a small pin-prick indentation in the upper left border, a touch of toning and a couple of tape remnants/tiny pulls on the reverse, otherwise fine.
 
A nicely-aged/gently-used example of this always-popular early-'67 Fillmore poster.
