So the museum’s “Wild Man of the Woods” mask, made in 1900 and previously identified only as “Kwakiutl,” will be attributed to Willie Seaweed, a Canadian carver who died in 1967. In another gallery an exhibition of more than 30 pieces of pottery will celebrate the extraordinary skill of Nampeyo, a Hopi woman born around 1860. Other objects, thought to be the work of single unknown creators — like a selection of Navajo “eyedazzler” weavings dated 1885-1900 — will be grouped together with labels reading, “Artist not known.”  New York Times
