While it just spans a portion of the far West, it supplies some interesting depictions. Not just for the territories and their towns and terrain, but the inclusion of the historic trails and roads. While it shows the Central Pacific Route of the Railroad that would soon help link across the nation, the notations for early wagon roads, explorers routes and even the southern "U.S. Mail Route" (which here is shown to weave a bit into Mexican Baja California) is unique. Hand colored by counties and complimented with a nice vignette of a wagon trail in northern Nevada.
Condition is very good. Image size is 14.25 x 25.5 (inches).
