A lithograph with hand colored wash.

Size: Approximagely 31 cm x 38 cm (11.75 inches x 14.75 inches)

Map Type: Atlas

This is an excellent copy one very small age spot, but retaining it's vibrant colors.

Following Mitchell's acquisition from Tanner in 1846, this map by C.S. Williams remained relatively unchanged until the publishing rights were sold to Thomas, Cowperthwait & Company in late 1850. This map was published shortly after the copyright was transferred from Mitchell.

No changes in this map from it's original issue by Mitchell are observed, except the inset map now reflects the borders established with the ¹"Compromise of 1850", and the territory has been renamed "New Mexico". This is the last issue of this Republic era style map with grant areas illustrated. Mitchell had an arrangement with J.H. Young for a "new" map of the State of Texas that Thomas, Cowperthwait & Co. would release with the next issue of the Universal Atlas in 1852.

Inset map "Texas north of Red River".
