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 incorporates Tasmania and New Guinea into the mainland. The title and dedication cartouches are tucked between the cusps, and the hemispheres are supported on the shoulders of two men. Panels of French text flank the map (18.8 x 11.0" including text). On a sheet of French text measuring 20.0 x 13.3".
A crisp impression on a sturdy sheet of watermarked paper. There is some minor soiling and a repaired centerfold separation and associated tiny tear that extends 0.5" into the image at bottom.
