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 excellent (B+) condition; a pair of small pin holes in the top corners, a couple of stray pin-prick marks in the lower left margin/corner and upper right margin, a tiny pinch ding in the top margin and a whisper of toning, otherwise fine.
This is one of the better-preserved 1st printing examples I have seen in recent years, very sharp indeed.
