This is a beautiful 1849 map of Pennsylvania by legendary American map publisher Samuel Augustus Mitchell. It covers from Lake Erie eastward to Delaware and New Jersey. An elevation profile of the important Pennsylvania Canal system fills the upper right quadrant of the map. In the lower left quadrant steamboat travel distances are rendered in tabular format. Features the state's cities, towns, roads, canals, railroads and other features in great detail. 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.
