DESCRIPTION: A spectacular, large (48" high) antique nautical chart of New York Bay and Harbor from 1889. Beautiful hand coloring enhances the attractiveness of this scarce and fine engraving. Two sheets professionally joined.
This chart was printed in 1889 from an electrotype copy of the original hand-engraved copper plate, a process the U.S. Coast Survey adopted around 1850. As a soft medium, copper plates could only withstand print runs of perhaps 200 copies before the plates wore down. To enable larger print runs, a mold of the original plate was created in wax or another soft medium. Then, using an electro-chemical processs ( electrotyping ), the mold was coated with a metal layer, typically copper. Printers were then able to produce output from the new electrotype copper copy, while preserving the original. Electrotype copy number 3.
