I remember everyone being completely amazed by the Great Moments with Mr. Lincoln exhibit at the '64 Fair. And I was awed by the Hall of Presidents the first time I visited Disney in the early 1980's. So I never imagined there were "talking Presidents" as early as 1933!!?? I can't find any other information about this exhibit in the guide books for the Fair, or from Google searches about Charles W. Clark or the exhibit.
Does anyone know anything more about this exhibit?
