Excerpt: Towards the end of World War II, U.S. intelligence officials were afraid that the German dictator would flee Germany by assuming a disguise. By 1944 the world identified the man largely by his trademark toothbrush mustache and oily side-slicked hair, so they ordered his portrait to be cloned.
The Office of Strategic Services (OSS), an early version of the CIA set up during World War II, asked Eddie Senz, a New York make-up artist, to produce the altered portraits after D-Day on 6 June 1944. Despite fears that Hitler would attempt to flee Germany, the portraits were never needed.
That’s a good call. Especially since they both have roughly the same amount of empathy and understanding of humans.
