A large, impressive 1942 Mercator projection world map published by Blondel La Rougery. The map emphasizes major airplane routes, with distances (in km) noted in red. Time zones and longitude are also indicated at top. A text box at bottom-left explains the Mercator Projection.
Despite the title, although countries’ names are noted, national borders are not emphasized and only continents are color shaded. It is worth remembering that this work was published during the Second World War, while Paris was under Nazi occupation, though the intended message of the maker, if any, is subtle.
The Bibliothèque nationale de France holds a printing of this map from 1941, while four institutions in North America hold the present printing (OCLC 48521114). We are aware of a 1948 printing (previously sold by us) and a 1957 printing as well.
