"This passport shows what the forgers were capable of producing. It also hints at their sense of humour and their opinion of Hitler and his beliefs. They've given Hitler's passport a red 'J' (which stood for 'Jew' on a German passport). He has a visa allowing his entry into Palestine, which was under British control at that time. The passport also describes Hitler's occupation as a 'painter'. Under distinguishing features, they list his 'little moustache'."
