This early map is titled 'A New and accurate Map of Connecticut and Rhode Island. from the best Authorities' published in the Universal Magazine in 1780. The map features Long Island Sound and Narraganset Bay, as well as old or unusual names for many places, including Block Island, which was labeled Block Rock Island, several embellished mountain ranges can be seen running through Connecticut, a decorative cartouche frames the title, and the map was published in the middle of the American Revolutionary War.You can also see parts of Martha’s Vineyard and Massachusetts on the map, as well as “Lands Granted to New York” along the left side of the map, which tells you a little bit abut the history of Connecticut and New York at the time. During the early 1700’s, New York and Connecticut often disputed the precise location of their shared border, leading to a border dispute that eventually gave the colonies their modern shapes. Though the dispute was officially resolved in 1731, effects of the boundary conflict persisted until well after both colonies gained statehood following the American Revolution.The map measures 13 1/4 x 16 1/2 in. wide, with two vertical folds, the text and features are pretty clean, with wear and creases along the edges and separations along the folds, and a diagonal crease in the lower right corner. A scarce map of Connecticut and Rhode Island from the Revolutionary War period, with an interesting history related to borders between two of the colonies.
