Heydrich images

Hello everyone,

I am a member of a documentary filmmaking team working on a project about Czech prodigy Petr Ginz. By the time Petr was 16, he had completed more than 170 drawings and paintings and authored five books. He spent two years in Terezin before being sent to his death at Auschwitz. Part of the film will focus on Reinhard Heydrich. To that end, we are looking for still and moving imagery of Heydrich. The National Archives has some material but I would be interested in hearing from any of you as to where the most extensive collection exists. I am also looking for any film or photos of the German occupation of the Czech Republic. Thank you for your assistance.
