Thomas, Cowperthwait & Co. "A New Map of the State of Illinois."

"A New Map of the State of Illinois." From Universal Atlas.

Philadelphia: Thomas, Cowperthwait & Co., 1850. 15 3/4 x 13. Lithograph transfer from engraved plate. Original hand-coloring. Very good condition. 

A strong, beautifully crafted map of Illinois from the mid-nineteenth century, published by Thomas, Cowperthwait & Co. This firm took over the publication of S. Augustus Mitchell's important Universal Atlas in 1850, and they continued to produce up-dated maps that were amongst the best issued in the period. This map shows a state beginning to come into its own, with development throughout the state. The maps issued by Thomas, Cowperthwait & Co. are known for their depiction of transportation systems and this map is no exception. The burgeoning network of roads, railroads, and canals is clearly depicted, connecting the many towns throughout this prosperous state. An excellent picture of Illinois at mid-century.
