This decorative double-hemisphere map was updated with the new astronomical observations of Chirikof and Delisle. The map features the Sea of the West and a Northwest Passage in North America and a conjectural shape for Australia. The title and dedication cartouches are tucked between the cusps; the hemispheres are supported on the shoulders of two men. The map is surrounded by a decorative rococo-style border, printed from a separate plate as the map. Brion was the former Geographer to the King of France, and Desnos was Geographer to the King of Denmark.
