Second state of Charles Desilver's map of the region west of the Misissippi River to west of the Rocky Mountains, issued in the latter part of 1856, with the new decorative border style characteristic of Desilver's maps.
Desilver's mid-continent map is a remarkably unique work for the time period. The map is rich with early immigrant information, Indian details, forts, roads, Indian Treaty notes, early explorers routes, Indian Battle grounds, Indian Reservations, trading posts and a host of other excellent notes and feaures. The map actually has its own symbol for trading posts, a rare appearance on a map of the period.
This map rarely appears on the market, as Desilver's atlas was not as widely distributed as others in the run and this format appears not to have been included in all additions.
