Original Frank Zappa and The Mothers concert poster from Frankfurt, Germany, dated 28th November 1971, These posters were sent over from Germany to advertise the ill fated '71 Rainbow Theatre concert, when Frank was thrown from the stage. Because the show sold out well in advance the poster was never used. Size about 600mm x 840mm, in EX condition, has been machine folded, now kept rolled, slight tear in fold at the top and bottom middle, but only about 15mm. Very rare poster.
