Map of the British and French North America, 1775
John Mitchell's map of North America. A similar map was used in negotiating the northeast boundary of the United States at the Treaty of Paris at the end of the Revolutionary War.
This map is dated 1775 but is the seventh version of the original, which was printed in 1755.
This large map was photographed in one piece using a digital camera and because of this most of the textual content of the map is not clear enough to read.
