United States, West, & Mexico, North.(Western states- California, Nevada, Utah, Arizona, Colorado, New Mexico, Kansas, Indian Territory, Wyoming). Issued 1883, London by Letts, Son & Co. Attractive and fascinating 19th century color lithographed map. Key locates British consuls and important light houses. A late re-issue of the SDUK plates from the 1830's & 40's, here transferred from steel to a lithographic process of printing, with amendments made to the maps during the process. Hence, Lett's firm did not merely re-issue the SDUK maps, but created entirely new maps using completely different printing technologies with unique and pleasing visual results. For instance, most SDUK maps were issued either in B&W or with narrow outline hand color, here the thick coloring altering the visual end result. Well preserved, nice looking example with pleasing age patina, fresh and almost as issued. Sheet Measures c. 14"H x 17"W. Engraved Area Measures c. 12 5/8"H x 15 5/8"W.
