Description:

Copper-engraved map, hand-colored in outline. 45.3x61.8 cm (17¾x24¼").

Uncommon reissue of Thomas Jefferys' map from 1761, based on Gerhard Mueller's map of 1758, which was one of the first to correctly depict the Kurile Islands and also suggest the outline of Alaska and the Aleutian chain. It shows detail of the Arctic coast of Siberia based on Vitus Bering's second Kamchatka expedition from 1733-43, and illustrates the sea routes made by Captains Bering and Chirikof. In the largely unexplored North America, the River of the West is shown extending to Lake Winipigon. A key at bottom left translates Russian geographical terms.
Condition Report: Short marginal splits at top and bottom of centerfold; near fine.
