S. A. Mitchell's 1849 map of Venezuela, Colombia (New Grenada) and Ecuador. Covers from the Bay of Panama to Brazil. Political and topographical features are noted and color coded with elevation rendered by hachure. The railroad across the Isthmus of Darien (Panama) is shown via an inset in the lower right quadrant. The whole is engraved and colored in Mitchell's distinctive style with green border work and vivid pastels. 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.
