1) Morse & Breese, 1845, printed color, Morse's North American Atlas ,15" x 12". This is a very nice, unfolded example of this early cerographic map with full printed yellow coloring. Wheat notes that this is the same map as published by the company in 1842. California and the western states are controlled by Mexico and shown as New California. Texas is Independent and the settlements of Austin, Nacogdoches, and S. Antonio de Bexar are located. This pre-Fremont map shows a large swamp in the area of today's Great Basin with rivers flowing across its expanse. The Great Salt Lake is here named L. Youia (salt) with the American Fur Depot on its eastern shore. With a large inset map "Central America and Yucatan."
2) Thomas, Cowperthwaite & Co., 1850, hand color, 15" x 12". Drawn by Samuel A. Mitchell, this pre-Gadsden Purchase map extends to include California, the large territories of Utah and New Mexico. A number of early towns are named including the Pueblo de los Angeles, plus three mission towns in California. Utah occupies all of the territory between California and the Continental Divide, while New Mexico Territory stretches between California and Texas. Names the Santa Fe Trail and the Great Spanish Trail (running between Santa Fe and the Los Angeles). Two insets: "Guatemala" and the "Valley of Mexico" with its two large lakes and Mexico City. Locates and names many Indian Tribes. Three short marginal tears at top, still fine.
