This is a beautiful 1849 Mitchell Map of Maryland and Delaware. Centered on Washington D.C., this map extends eastward from Maryland to New Jersey and the Delaware Bay. The Chesapeake Bay is rendered in full. In the upper left quadrant of the map, a table details various lists of steamboat routes. In the lower left quadrant data from the census of 1850 is presented in tabular form. The whole is engraved and colored in Mitchell's distinctive style with green border work and vivid pastels. Political and topographical features are noted and color coded with elevation rendered by hachure. Mitchell published this chart in his atlas from 1846 to the late 1850s before discontinuing the series and selling his map plates to DeSilver. This map was issued in the 1849 edition of the New Universal Atlas. It was the last edition of that atlas to be published by Mitchell prior to selling the plates and rights to the atlas to Thomas Cowperthwait in 1850.
