Scale approximately 1:1,490,000 ; "Scarce cartographic propaganda poster warning Germans of the potential destruction their country would face if British warplanes were based in Belgium. The poster warns of the dangers of Belgium being used as a launching pad for air attacks on Germany, arguing that Germany's industries would be vulnerable to immediate destruction. The poster features a montage of biplanes bombing factories, as well as a map of Belgium with red radiating from it. As the map shows Metz as part of Germany, it is likely that it was produced prior to the formal implementation of the Treaty of Versailles in 1919, though France assumed control of the city in 1918. The poster features images of Nieuport biplanes of the variety that were in service after 1916, suggesting that the poster was likely created during the latter part of the war. The poster was likely created as a way of communicating to the German public the future strategic disadvantage Germany would face if it were to concede defeat."--Edited description of Barry Lawrence Ruderman Antique Maps. ; Includes color illustrations. ; Shows Belgium and industrial areas of western Germany. ; Likely published 1918.
