With an unusual appearance of "Neu Orleans" Territory.

Rare late state of Gussefeld's map of the United States, published in the same year as the Louisiana Purchase and highlighting Jefferson's United States on the eve of the expeditions of Lewis & Clark, Zebulon Pike, etc.

Following the Louisiana Purchase in 1805, there was a tremendous push to chart and explore the new American West. Gussefeld's map is illustrative of the extent of contemporary knowledge of the area purchased by Jefferson in 1803, including conjectural mountain ranges in the regions north and south of the Missouri River, scattered Indian Tribes and lots of conjecture.

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 the earliest to depict the results of Lewis & Clark and Pike's discoveries, which were first reported on the 1812 edition of the map.
