A huge subway-sized concert poster advertising the February, 1968 American Folk Blues Festival concert in Frankfurt, Germany, with an all-star bill featuring John Lee Hooker, T-Bone Walker, Jimmy Reed, Big Joe Williams, Curtis Jones, Eddie Taylor 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 tiny, invisibly repaired edge tears.  Extremely impressive in person.  See our other listings for a 1969 American Folk Blues Festival featuring Magic Sam and Clifton Chenier, among others.
