Scarce Charles Desliver map of Michigan, hand colored by county and showing towns, rivers, bays, lakes, railroads, roads, distances, etc. Tables of Steam Boat routes and distances.
A number of Michigan Counties still not yet formed. Railroads are shown in Red and Canals in Blue
A nice example of this increasing difficult to obtain map, from Thomas Cowperthwait's version of Mitchell's Universal Atlas.
An unusually clean fresh example.
