Berlin's mayor has expressed concern at Madame Tussauds' plans to include Adolf Hitler among prominent Germans who will be immortalized in wax at its new museum, his spokesman said Monday. Klaus Wowereit has written a letter to the wax museum's curators urging them to consider carefully whether to include the Nazi dictator and, if they still do, to be careful how they present him, spokesman Guenter Kolodziej said Monday. "In the mayor's view, he should not be shown as a cult figure," Kolodziej said. Madame Tussauds' Berlin museum is scheduled to open on July 9. It will be located on the Unter den Linden boulevard, close to the German capital's landmark Brandenburg Gate.
