Remarkable Sea Chart of the Gulf and Western Caribbean
Nice example of Blunt's blue backed sea chart of the Southern Coastlines of the United States, from Texas to Florida, along with a highly detailed treatment of Cuba and the Bahamas, first published in 1845.
The map provides a remarkably primitive early depiction of the Florida Coastline, pre-dating the results of the Surveys undertaken in the 1850s and 1860s by the United States Coast Survey.
The chart includes 10 inset maps and harbor plans, including the harbors of Puerto Rico, St. Thomas, Rum Key, St. Martin's Harbor, Turks Island Anchorage, Havanna, Matanzan, Ragged Islands, Mayaguez, and Tampico.
Originally drawn when Texas was still a Republic. Includes numerous soundings and compass roses.
Blue backed sea charts were intended for use at sea and very rarely survive in such nice condition.
