One thing is for sure--this pamphlet, which has no place of publication or date--was definitely a German war propaganda effort, printed in English, published in Germany, and I guess distributed wherever the English-language-winds and luck would take it. My copy come from a collection that I purchased from the Library of Congress, and it is luckily stamped August 6, 1940, for the date it was received by the library. So the summer (or earlier) of 1940 is the date: the Battle of Britain had begun in July, Dunkirk had been evacuated June 4, France surrendered a few weeks later, and the war was not going well for the U.K. Germany was still a year away from their disastrous attempt to conquer the Soviet Union with Operation Barbarossa, and at this time in 1940, the U.S.S.R. was its vital trading partner. Great Britain was waging a successful economic war/blockade against Germany, which was without any real finance and with no reserves to purchase foreign goods, so in spite of the successes of the invasions and Blitzkreig, the Brits were enjoying a certain level of success. And so this pamphlet appears, one of others, a small part of a hearts-and-minds campaign to try and apply pressure to Britain's allies to convince her to sue for peace.
The main thrust of the maps of the pamphlet was to show Germany surrounded by not-threatening allies, pillowed by neutrals and countries it had overtaken (with no attempt made to label Poland). The interior map (above) is a very faint attempt to show the comparative strength of Germany being surrounded by neutrals in 1939 as compared with being surrounded by enemy countries in 1914. The message of course was that Germany was strong in 1914-1918 in spite of the "threatening" neighbors, so with relatively benevolent neighbors in 1939 they would be even more effective as a war-making national machine. Perhaps this had some influence somewhere, maybe among the Vichy French. And some elements in the U.S.
The Nazis certainly liked their red.
