A man looks at an antique tribal mask, Tumas Crow Mother, circa 1860-1870, revered as a sacred ritual artifact by the Native American Hopi tribe in Arizona, which is displayed at the Drouot auction house ahead of a sale in Paris December 9, 2013. The Hopi, some of whose 18,000 members continue to follow a traditional way of life farming on three isolated mesas, believe the bright, mostly fabric masks are imbued with the spirits of divine messengers.
