Rare historical / pictorial map of Western portion of the Butterfield Mail Route, drawn by Robert A. Hanson.
The map was likely published by the Western Cover Society, a California based society which published the Western Express. Hanson's maps were advertised for sale in this journal as early as 1969.
The map provides an elegant overview route, with daily stops and distances given from Hueco Tanks and El Paso to San Francisco.
The map is now apparently quite rare. We were unable to locate another example.
