Johnson and Ward produced this steel plate, hand colored map for Johnson's New Illustrated Family Atlas in 1860 The city is laid out in black ink with districts highlighted in pastel pink, green and yellow. Other details include lakes, rivers, railroads and the names of streets, monuments and parks. Outside the map are sketches of the Smithsonian, the Capitol and the Washington Monument. Alvin Jewitt Johnson was a well known cartographer for nearly a quarter of a century. His maps have become prize collectible and are considered true works of cartographic art. This measures 18" x 14_� and is printed on a heavy grade of paper now somewhat yellowed with age. There is one very small archival tape repair in the right margin. Another copy of this map is available through an antiquarian map dealer for $275, but I obtained it as part of the Maryland attorney's collection which I bought a few years ago, so can let it go for less.
