Fearful that Nazi leader Adolf Hitler would attempt to flee Germany, US intelligence tried to predict what the Führer would look like if he altered his appearance.
The Office of Strategic Services, a precursor to the CIA, hired American make-up artist Eddie Senz to alter Hitler's portrait in various guises.
Senz's altered images were circulated among Allied forces before the D-Day invasion in June 1944.
The pivotal Normandy invasion was one of the largest amphibious military assaults and predicting Hitler's reaction was part of the Allied forces' extensive planning.
During the 1990s, German news magazine Der Spiegel first released Senz's photos to the public.
Here are Senz’s head shots of the Führer in numerous guises.
