One of theater's offerings for the summer of 1933 was the production of "Peace Palace" by Emil Ludwig (1881 - 1948). Posted here is a review of that staging along with a black and white photograph of the cast in full costume and recognizable make-up.
"Herr Ludwig's scheme is simple. He takes the chief events of the Versailles peace conference and places them with all necessary license on the stage; and he seeks, by all the dramatic devices which he can contrive, to make his characters appear the frail human-beings they were, rather than the wise and disinterested statesmen they pretended to to be."
