Beautiful example of Coven's & Mortier's edition of the first printed map to accurately depict the course and mouth of the Mississippi River.Covens & Mortier's map is based upon De L'Isle's Carte du Mexique, which was drawn from the reports brought back to France from the survivor's of the La Salle expedition into the interior of North America and from information derived from the explorations of Bienville and d'Iberville. De L'isle map is an important map on the development of the mapping of America. . De L'Isle's map also includes greater accuracy in the Great Lakes region and in its depiction of English settlements along the East Coast. Excellent detail of the Indian villages in East Texas, based upon the reports of Iberville and the Spanish missionaries. The best depiction of the Southwest to date, w/ early trails & Indian tribes. Cumming described the map as profoundly influential.Original outline colour.Near mint condition.Ref: Martin & Martin, Maps Of Texas And Southwest, cf. pp.92-93.
