Mitchell, S. Augustus “Map of the State of California, The Territories of Oregon & Utah, and the chief part of New Mexico"

S. Augustus Mitchell. “Map of the State of California, The Territories of Oregon & Utah, and the chief part of New Mexico.”  From Universal Atlas.  Philadelphia: Thomas, Cowperthwait & Co., [1850]-1851.  With copyright info  H.B. Burroughs, 1845.  15 1/2 x 12 7/8.  Lithographic transfer from an engraved plate.  Original hand color.  Right hand margin trimmed close to neat line.  Else, very good condition.   A mid-century map of the western part of the United States, one of the first maps to show the state of California and the territories of Utah and New Mexico.  The map is an updated version of a map that appeared in S. Augustus Mitchell’s Universal Atlas of 1849.  The southern part of the region shown in that map, “Upper California,” had just been won from Mexico in 1848, and Mitchell’s map was important for presenting the vast new U.S. territories to the American public.  In 1850, the rights to Mitchell’s atlas were sold to the firm of Thomas, Cowperthwait & Co., which
