Nampeyo's earliest recorded pottery was made
 around 1896.

Her fascination with ancient Hopi symbols that she saw on pottery shards around the Sikyati ruins and her desire to produce similar work... was eagerly greeted with pottery orders from local Indian traders and merchants.

Nampeyo is considered a key figure in the evolution of Southwestern pottery.  Her descendents work has (for the most part)
remained true to her original pottery designs and is eagerly sought by collectors and museums.

Perhaps, the best book on the subject (which we stock) is
"The Legacy of a Master Potter - Nampeyo and her Descendants".
