One notable exception to his perennial portrayal of Charley Weaver was his characterization of Mrs. Butterworth of syrup fame. He dressed as the brand's "old lady" icon, affected an obviously falsetto voice ("Hello! Mrs. Butterworth here!") and continued to sport his moustache. A Civil War buff, in the 1950s he opened the Charley Weaver Museum of the Civil War in Gettysburg, Pennsylvania. The museum was housed in a building that had served as headquarters for General O.O. Howard during the Battle of Gettysburg, and remained in operation for about ten years. The site later became the Soldiers National Museum, and closed in early November 2014.
