"Geographische Verbreitung der Menschen-Rassen. Ubersicht der Nahrungsweise und der Volksdichtickeit in den Ackerbaulandern; auch Manches zur Physik des Menschen", Perthes, Justus
This scarce and unusual thematic map illustrates the geographic distribution of the human races throughout the world. It is drawn on Mercator's Projection with well-rendered vignettes of the various races at top and sides. Beneath the map are related graphs and a smaller world map showing population density in relation to agricultural zones. Berghaus' Physikalischer Atlas was a monumental work in the history of thematic cartography. It is considered the first comprehensive physical atlas of the world.
