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. Good for towns and terrain of the area, as well as unusual territorial boundaries for Nebraska, the "L" shaped Washington, the confederate territory of Arizona, amongst others. Here, Alaska is still part of the "Russian Possessions". A large notation spanning through the western plains still states "The Great American Desert".
