This map is similar to an article that appeared three years earlier in the New York Times. The Times of March 17, 1935, reproduced this map and reported that, "This Map, entitled 'Deutsches Grenzland In Not' (German Frontier Districts in Distress) Is Distributed by the Nazi Ministry of Propaganda and Hangs in the School Rooms of Germany." ID #1245, "A Geography Lesson for Young Germany."
For a similar warning in Life Magazine in 1938, see ID #1266, The Key Nazi Map of a Greater Germany.
For an earlier, poster-sized version of the same map, see ID #2040, "Das ganze Deutschland soll es sein!" (It Should/Shall All Be Germany)."
