Propaganda Maps

Propaganda as defined by the American Heritage Dictionary is
  "Official government communications to the public that are designed to influence opinion. The information may be true or false, but it is always carefully selected for its political effect."

When maps are used for this purpose they fall into the category of propaganda maps. This map was used by the Nazi Party in the 1930s to make it seem as if the countries surrounding Germany were threatening it, influencing the population to be further in favor of war. Upon first glance it certainly looks as if Germany is unfavorably surrounded.
