A nice map showing early territorial and state borders in the Southwest. California had just become a state in 1850 and Texas is presented with its final, post 1850 borders (while the coloring shows an oversized Texas, the engraved lines show the final borders). A notation (in German) in the panhandle of Texas shows the "summer range of the Comanches." The topography in the Southwest and Great Basin region is mostly spurious. The map extends to include all of Central America, with a key at bottom.
On a bright sheet with some faint scattered foxing at center and a crease in the bottom right corner of the sheet.
