A large and uncommon pocket map of the territory that details the post offices and mail routes throughout the territory. The routes are shown with different colors to depict the frequency of service, from once a week to six times a week, including special services and mail messengers. The legend also locates discontinued post offices, electric power lines, and more. The smaller example of this map is fairly uncommon, while this large format edition is a rarity. The logo of the Post Office Department, featuring a pony express rider and a train is above the title. The map folds into gilt-stamped, black cloth covers.
