Railroad promotional map showing the western U.S. from Colorado, New Mexico and Wyoming to the Pacific.
The map offers notable system details, including indications for standard gauge and narrow gauge, with three rails and connecting lines.
The verso of the map is covered with printed information on the D. & R.G. and the region it covers, including a comparison of Colorado and Switzerland – Colorado comes out slightly ahead.
OCLC/WorldCat lists only four copies, but all dated 1910 – there are no listings of this 1911 issue.
