“IOWA” New York: Charles W. Morse and Samuel N. Gaston, 1857. Original wax-engraved map, with original hand color from The Diamond Atlas. (Image: 5 x 6’’)
This map depicts the new State of Iowa (statehood 1846) with the counties named and in contrasting colors.
Topographical features are shown, and major cities, towns, and railroads (existing and proposed) located. It is very detailed for its miniature size (approximately 50 miles per inch).
The wax-engraving method was developed by Sidney E. Morse (brother of Samuel F. B. Morse - inventor of the telegraph). Wax engraving was “a major techno-logical breakthrough that greatly influenced American commercial map and atlas production in the U.S.” (Schwartz: Mapping of America, p. 265). This map is an early example of the process.
