Joseph Keppler: Puck Magazine 1877
Joseph Keppler... The Theatre of War – The Latest Spectacular Tragedy (Puck Magazine Centerfold; Vol. 1 No. 9, May 9, 1877). "...In the lower box on the left, Franz Joseph I of Austria stands next to England's John Bull. Across from them on the right, sits Otto von Bismarck, Chancellor of Germany. Between them a skeleton conducts an orchestra of cannons, bombs and rifles. Above the stage, a hydra-headed plaque surrounded by the legend Theatrum Mundi (Theatre of the World) is flanked by skulls and bones that drip blood onto the stage." From Joseph Keppler: Puck Magazine 1877.
