This is my favorite Florida map.  Actually it is a series of maps showing the Development of Florida Counties from 1820 to 1936.

The map is located in the University of Florida, George Smathers Libraries, Map Collection.  It is from the Florida Works Progress Administration and assembled by the Historical Records and State Archives Surveys.  Click on the image to view the original.
