Alex Miller - otherwise known as Sonny Boy Williamson - brought his blues harmonica across the big pond from his native Mississippi to the Galaxy Club in England for a Christmas-week show in 1964. This poster mounted on linen heralds the performance in bold block letters, along with the Muleskinners and the Troggs, who formed that year and whose name was missing a "G" here. Measures 23" x 33.5" and is in NRMT condition.
