English: This scarce hand colored map is a lithographic plan or map of Philadelphia dating to 1846 by the legendary American Mapmaker S.A. Mitchell, the elder. Depicts the entire city in stupendous detail with even important buildings, streets, piers, and canals drawn in. This is a rare transitional map produced by the mysterious engraver H. N. Burroughs, whose work for the Mitchell firm appears in 1846 between that of H.S. Tanner and Mitchell himself. Ristow notes, Nothing is known about Burroughs, but he was undoubtedly an employee or associate of Mitchell. His fine and detailed work appears only in the hard to find 1846 edition of the Mitchell’s Atlas and evinces a more delicate hand than later editions. Dated and copyrighted 1846.
