Johnson's New Jersey, Johnson's Delaware and Maryland Illinois Eight engraved coastal elevation viewsThis is a colorful atlas page with 2 separate maps from Johnson's Atlas published in either 1870 or 1871 (I have not found a way to distinguish between these two years) showing great details of the States of New Jersey on one map and Delaware and Maryland combined on the second page. Colored by counties, this map shows railroads, roads, places, towns, canals, rivers, and some detail on neighboring states. A great resource for all kinds of information
