Attractive large format map of the US & Mexico on the eve of the Civil War.
Includes marvelous ephemeral western territorial border. California is oddly shaped, extending only to the Sierras. Massive Utah Territory, with New Mexico Territory to the East. Washington Terr. Extends to the Rocky Mountains. Nebraska Territory extends form the Rockies to the Missour. Texas is oddly configured and the French colony is highlighted in Blue. Pre-Gadsden border w/ Mexico.
Minor loss at centerfold, but still a good example. Normally a $400 map.
