Pair of very attractive hemisphere maps, each surrounded in a rococo style border that was printed from a separate copper plate. In the Western Hemisphere Brion has devised an ingenious way to show the competing theories of the Pacific Northwest; one engraved in hachure and colored in yellow, and the other engraved in dotted lines and colored in green. The yellow version shows the Sea of the West and Northwest Passage. In the Eastern Hemisphere, Australia is partially mapped and then completed into an odd shape by hachures connecting Tasmania and New Guinea. Both include numerous exploration routes with notation of important recent discoveries.
