How the scale of WWI was explained to people in the US.
According to NYPL, the creator of this map, the London-based Stanford’s Geographical Establishment, was a prolific commercial publisher of maps whose aim was to elucidate various aspects of the war to the public. Their maps were known for the creative way they represented this information. A number of them use an interesting technique which helps contextualize geographic information about the war by means of comparisons with geographical regions more familiar to the viewer. Above is an example that illustrates the scale of the fighting in Europe by superimposing a map of the major European fronts over a map of the continental United States.
