Rare Civil War era map of the United States, published in Philadelphia by Charles Desilver.
The map includes inset maps of Washington D.C., Virginia, Maryland and Delaware, and the Vicinity of Annapolis.
Includes a list of all the Military Forts and other installations in each state and territory, including those in the western territories and Texas.
The map is apparently very rare. OCLC locates only 2 examples, State Library of Virginia and Cleveland Public Library.
