This scarce map is one sheet of von Euler's four-part map of North America. This sheet covers the region from the Mississippi River valley through the American Southwest. It stands alone with a decorative cartouche and border. It presents a detailed view of French Louisania and the Spanish possessions in New Mexico with a Great Space of Land Unknown and Tecas in between. A notation on a river flowing into Lake of the Woods (The Wood Lake) remarks, "Great River coming from the West discovered lately by the Oshages Savages." A large inset map illustrates Hudson and Baffin Bays with numerous English notations concerning discoveries in the region. Euler's engraved "cum privilegio" stamp is at top right.
There are a few small spots and minor creasing at right.
