Rare wall map of North America, which appeared in Andriveau-Gougon's Atlas Choix .
The configuration of Texas is quite unique, reflecting the status of the debate over the eastern part of New Mexico, which would be resolved the following year with the 1850 Compromise.
The map also shows a final look at the pre-California Gold Rush Transmississippi West, with a massive "Nouvelle Californie," shown, along with Oregon Territory, but still no sign of what would become Utah Territory and New Mexico Territory in 1850.
Ozark District, Mandan District, Osage District, and Grand Desert dominate the West.
A fine depiction of Texas and the Transmississippi West in the year after the conclusion of the Mexican War.
