The color map of western NC above is from 1920. It labels places within ten miles of here with names I 'd never heard before and I thought I'd heard 'em all, but - Jerd... Dean... Custer...???? Very intriguing map.
And then there's "Drainage Map of the Appalachian Region"... It's from no later than 1911 and slightly rotates the normal view of the eastern US to display the topography and waterways flowing from the Appalachian range.
Anyhow...nice source of obscure maps from all over.
