Original 1st printing 14 x 22" concert poster for Frank Zappa & the Mothers of Invention appearing with the Sensational Alex Harvey Band at the Spectrum Theatre in Philadelphia, PA on 11/3/1975.

 Designer unknown/not credited (Discreet Records tour blank), medium-thick glossy-coated index stock poster is in very good to excellent (B/B+ to B+) condition; there are a couple of thin diagonal bends in the right margin, plus a few tiny handling creases/fingerprint smudges/thin stress bends hiding within the image/outer margin area and a large tape pull/shadow on the top margin of the reverse side, otherwise fine.

 VERY cool (and SCARCE!) mid-'70's Zappa poster from Philadelphia. Check out the show HERE:
