Two maps, one inset into the other. The inset map is based on a world map by Plancius issued in 1641, while the larger map is based on Visscher's map of 1612. Other than a recognizable Baja California, the maps are filled with the cartographic myths of the 17th century. The northwest coast bulges too far to the west. Both maps feature the seven cities of Cibola. Ref: Wheat (TMW) #159, Wagner (NW) #632, and Pedley #473. Bit of toning along one fold, else fine.
