Frog fetish with coral eyes: Coral and spiny oyster, both of the ocean, often combine with turquoise for dramatic color contrast. Collection, Museum of Indian Arts and Culture; gift of Charmay Allred. In the background: Ancestral Pueblo olla, ca. AD 1000–1100, found north of Pueblo Bonito in Chaco Culture National Historical Park in northern New Mexico. The line design is called “hachure” and symbolizes the color bluegreen, indicating water and sky. Acquired from C. G. Wallace. Photo by Kitty Leaken.
