Johnson's Pennsylvania Virginia Delaware and Maryland.
The Johnson company was one of the better American mapmakers of the 19th century, and were known for keeping current with all the changes that were occurring. This is a fine example of their work with bold original hand color. This early Civil War era map is a favorite for the area with the unsplit Virginia and several nice vignettes for "University of Virginia", "Dismal Swamp Canal" and a view of the "City of Baltimore".
Condition is very good. Image size is 17 x 24 (inches).
