1887 (dated) 21.5 x 15 in (54.61 x 38.1 cm)
A fine example of William M. Bradley's 1887 map of Washington and Oregon. The map covers both states in fine detail along with parts of neighboring California, Nevada and Idaho. The map also delineates survey grids referencing the work of the U.S. Land Survey. Also noted are various cities, towns, rivers, American Indian reservations and settlements and an assortment of additional topographical details. Map is color coded according to territorial and political boundaries with elevation rendered by hachure. Copyrighted 1887 by Wm. M. Bradley & Bro., as plate no. 93 in the 1890 edition of Mitchell's New General Atlas.
Bradley, Garretson & Co. (fl. c. 1880 - 1900) were prominent cartographic publishers active in the later part of the 19th century. Bradley acquired Samuel Augustus Mitchell Junior's atlas plates in the late 1880s which he used to publish his own version of Mitchell's atlas. The firm had offices both in Philadelphia, at 66 North Fourth Street, and in Brantford, Ontario.
Samuel Augustus Mitchell (March 20, 1792 - December 20, 1868) began his map publishing career in the early 1830s. Having worked as a school teacher, Mitchell was frustrated with the low quality and inaccuracy of school texts of the period. His first maps were an attempt to rectify this problem. In the next 20 years Mitchell would become the most prominent American map publisher of the mid-19th century. Mitchell worked with prominent engravers J. H. Young, H. S. Tanner, and H. N. Burroughs before attaining the full copyright on his maps in 1847. In 1849 Mitchell either partnered with or sold his plates to Thomas, Cowperthwait and Company who continued to publish the Mitchell's Universal Atlas. By about 1856 most of the Mitchell plates and copyrights were acquired by Charles Desilver who continued to publish the maps, many with modified borders and color schemes, until Mitchell's son, Samuel Augustus Mitchell Junior, entered the picture. In 1859, S.A. Mitchell Jr. purchased most of the plates back from Desilver and introduced his own floral motif border. From 1860 on, he published his own editions of the New General Atlas. The younger Mitchell became as prominent as his father, publishing maps and atlases until 1887, when most of the copyrights were again sold and the Mitchell firm closed its doors for the final time.
