A British poster purporting to show the Nazi plan of European conquest, with Great Britain "to be German before 1948." The message is unambiguous: "Grab! Grab!! GRAB!!! That's the Nazi Policy." The support for the poster is a "Secret Nazi Map - circulated in 1937" (not further identified). In fact, "it is highly unlikely that the Nazis would ever have allowed something as incendiary as this map to be printed or disseminated. It is more probably that it was invented by the anonymous propagandist to lend credibility to his message." Curtis 2016, 115.
Based on the last line of the timeline in the lower right ("Now the policy of 'Grab - Grab - Grab" is at last halted"), this map was apparently issued during the "Phony War" quiet between the fall of Poland in September 1939 and the invasion of France and the Low Countries in May 1940.
