Original 1st printing 4&3/8 x 6&5/8" postcard-backed concert handbill for the Mothers of Invention (featuring Frank Zappa) appearing with the James Cotton Blues Band at Bill Graham's Fillmore East in New York City on 4/19-20/1968; Design by Helen Heish, image is # 4 in the Bill Graham/Fillmore East series. Thin flat index stock postcard is in absolutely fantastic near mint (A-) condition; aside from a tiny handling mark and bump in the upper left corner, this is pretty much about as crisp/sharp an example as you can hope to find. For whatever reason, this seems to be one of the more difficult-to-find Fillmore East cards (the poster comes up fairly often).
