Original 1st printing 13&7/8 x 22" concert poster for the Mothers of Invention (featuring Frank Zappa) appearing with B.B. King and Booker T. & MG's at the Fillmore Auditorium and Winterland in San Francisco, CA from 6/6-8/1968.
Art by Robert Fried, image is # 123 in the Bill Graham/Fillmore series.
Medium flat index stock poster is in absolutely GORGEOUS mint/near mint to near mint (A/A- to A-) condition; other than a stray fingerprint or two, it is an extremely sharp example of this very trippy Bob Fried Fillmore poster.
