Ramos Polychrome ceramics were produced in the Casas Grandes region of Chihuahua, Mexico from A.D. 1250 until the region was abandoned around 1450. They are characterized by fine-line red and black designs and are considered the pinnacle of the Casas Grandes polychrome ceramic tradition. Photo by Susan Dial.
