Fascinating post-Lousiana Purchase map of the United States.
The map depicts a single Mississippi Territory, 2 years prior to the creation of the State of Alabama. The map also provides an early depiction of Indiana (1 year after statehood) and Illinois Territory (1 year before statehood). New Orleans Territory is still shown (5 years after Louisiana Statehood).
The present map is a modified version of an early map of Gussefeld and one of hte earliest to depict the results of Lewis & Clark and Pike's discoveries, which were first reported on the 1812 edition of the map.
