Unrecorded issue of Gibson's fascinating wall map of the Western hemisphere
Unrecorded intermediate state: conforms to Stevens and Tree 3c, i.e. title, imprint, printing of Articles from the 1763 Treaty, etc., though the United States is shown with engraved dotted lines and the country has lettered: "United States", as per Stevens and Tree 3d.
This post-Revolutionary War wall map of North and South America gathered together geographical material from D'Anville, Jefferys and Thomas Pownall, and incorporated the new political divisions brought about by the establishment of the United States. As per the 1783 Treaty of Paris, the United States is shown with its western border at the Mississippi and northern border extending through the Great Lakes. In the inset titled: "The Continent and Islands of America...", the United States of North America heads the list with its 13 states and "The State of Vermont, and all the Lands between the Lakes, the Apalaches & the Missisippi": the term "State of Vermont" refers to its status as a separate republic. (Vermont joined the United States in 1791). "All the Lands between the Lakes..." etc. would soon be settled, not to say over-run by a flood of white settlers bringing about the multitudinous conflicts with the Native American tribes who are regionally designated on the map.
Extremely well supplied with placenames and details, the Gibson map represents the sum of cartographical knowledge of the Americas for the 18th century.
