An engraved map, with full color wash

Size: 15-1/2 inches X 12-1/2 inches.

Map Type: Atlas

This is an excellent copy, with vivid colors. Some stains in the margins, age spots in southern Utah and southern Oregon.

Thomas, Cowperthwait & Company of Philadelphia purchased the copyright of the New Universal Atlas from Samuel Augustus Mitchell, Sr. in 1850. Taken from this atlas, this map is attractive and legible, and is a particularly scarce variant of the West.

The west is illustrated after the war with Mexico and just before the discovery of gold in California. The boundary with Mexico is shown at the Gila River prior to the Gadsden Purchase of 1853. Many Indian tribes are named.
