A huge subway-sized concert poster advertising the October, 1969 American Folk Blues Festival concert in Hamburg, Germany, with a bill featuring Magic Sam, Clifton Chenier, Whistling Alex Moore, Earl Hooker, Juke Boy Bonner and others.  The poster, with artwork by the legendary German poster artist Gunther Kieser, measures 33″ x 47″, and is in excellent condition, with some minor edge fraying and a few small, invisibly repaired edge tears.  Extremely impressive in person.  See our other listings for a 1969 American Folk Blues Festival featuring John Lee Hooker, T-Bone Walker, Jimmy Reed and others.
