Original 1st printing 14 x 20" concert poster for the Mothers of Invention (featuring Frank Zappa) appearing with Oxford Circle at the Fillmore Auditorium on 9/9/1966 and at the Scottish Rites Temple on 9/10/1966, both in San Francisco, CA.
 
 Art by John H. Myers, image is # 27 in the Bill Graham/Fillmore series.
 
 Medium flat vellum stock poster is in good to very good (B to B/B+) condition; there are tack holes in all four corners, along with a couple of hairline-thin diagonal bends along the lower left margin and and in the upper left corner (about 3" and 5" long, respectively), a few tiny pin-prick spots and light/soft smudges scattered around the outer margin area, a hint of mild paper toning, a light surface scratch or two and a series of light tape pulls on the reverse side, otherwise OK. 

  Pretty nice-looking 1st printing example of this fairly early (late-'66) Fillmore poster, the colors are still REALLY strong on this one.
