Johnson's Michigan and Wisconsin.
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. With a vignette for the "Straits of Mackinaw" this map covers these Great Lake states with good detail for towns and basic terrain.
Condition is good with top and bottom margins close. Image size is 17 x 24 (inches).
