This is an attractive 1849 example of Mitchell's map of Louisiana. It depicts the entire state color coded according to individual counties. Shows canals and roads with notations regarding steamboat and overland mileage. A large inset in the upper right hand quadrant offers a detailed city plan of New Orleans. Shows grid structure, districts, important buildings, piers and wharfs. 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.
