Original 1st printing 12&3/4 x 21&7/8" concert poster for the Mothers of Invention (featuring Frank Zappa) appearing with the Chambers Brothers and Tim Buckley at the Fillmore Auditorium on 12/14/1967 and at Winterland on 12/15-16/1967, all shows in San Francisco, CA. Art by Stanley Mouse and Alton Kelley, image is # 97 in the Bill Graham/Fillmore series. Medium-thick flat index stock poster is in spectacular near mint (A- to A-/B+) condition; just an ultra-light amount of handling/edge wear (a few pinch dings and tiny bends in the top left/bottom right corners) and that's pretty much it... you'd be hard-pressed to find a sharper example without the "B. Graham" credit scratched into the plate. GORGEOUS original 1967 Mouse/Kelley poster from the Fillmore/Winterland.
