A most fascinating production, this is a fine example of the 1907 first edition of the Berthrong / Bond map of the United States showing exploratory routes and improved roads. The base map is a reduction of the General Land Office map of the United States issued annually from 1899 to illustrate the extending and progress of the Public Surveys. That map has here been overlayed with color-coded routes illustrating the most prominent explorations from the 1500s through the mid-19th century. In addition, it shows important roads then in being built or improved, including the National highway, Braddock Road, the Great Trail. The map was intended to demonstrate the current state of geographical knowledge and underscore the fact that - by 1907, little was left unexplored. (more details)
