By Capt. O.C. Overman. Unusual map beginning in Austin and depicting the route, connecting several Army forts, to Yuma. Incredible detail of water holes, grazing areas, missions, camps, Indian villages, and mines. Two sheets joined and folded as issued. Lists four authorities including Gillespie's Map of Texas (1867) and Gildart's Journal.

This example is toned with the paper being a bit brittle requiring care in handling - the map itself is very good.
