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. Here a map of the Austrian Empire and its nearby neighbors of the Balkans and Greece. An inset shows Crete. A vignette shows the "Mosque of St. Sophia".
