This map presents a very interesting, if somewhat twisted projection. A long Northwest Passage, a system of rivers and lakes, reaches across from the Great Lakes towards the Pacific. The northwestern part of North America is otherwise left blank. A most decorative cartouche adorns the otherwise scientific looking map.

A couple of spots and some text offsetting, otherwise very good.
