This map gives a list of the thirteen original states, with Vermont and the proposed names of the ten new states provided for in the Jeffersonian ordinance of 1784 - the first map to do so - being Silvania, Michigania, Chesonesus, Arsenistpia, Metropotamia, Illinoia, Saratoga, Washington, Polytamia, and Pelisypia.
The United States is outlined in green, British territories appear in red, and Spanish lands in yellow. The United States extends westward to the Mississippi, beyond which Louisiana has been granted to Spain. So too has Florida and the French colonial seat of New Orleans.
The map is highly detailed, extending to the Rio Grande and including notes on the Sioux Indians and the Country of the Padoucas. Extensive notes throughout, including notes on early explorers such as De Soto and La Sale, Indians, Forts and other points of early interest. Mississippi is marked as the western border, but the map extents till Mexico and naming "Tecas".

The map appeared from 1786 on in the supplement of de Vaugondy's Atlas Universel with the name of Boudet, later with the name of Delamarche.

Gilles and Didier Robert de Vaugondy

Gilles Robert de Vaugondy (1688-1766) and his son Didier Robert de Vaugondy (1723-1786) were leading cartographers in France during the 18th century. They served both as geographer to the king of France. The father, Gilles is also known as ‘Le Sieur’ or ‘Monsieur Robert’. He descended from the Nicolas Sanson family through Sanson's grandson Pierre Moulard-Sanson, from whom he inherited Sanson's cartographic material. After Hubert Jaillot died in 1712, the de Vaugondy's acquired numerous copies of his maps and plates, which formed the basis of their beautiful Atlas Universel (1757).
Their business flourished from 1731 to 1778. They made a substantial contribution to the world of cartography.
