Margaret Gutierrez and Luther Gutierrez were brother and sister from Santa Clara Pueblo, NM. They collaborated in making polychrome style of painting that they learned from their parents; Lela and Van Gutierrez. Their slips are unique in color and combination. This vase features the Avanyu (water serpent) with intricate detail and color. The detail is very fine and colors are brilliant against the tan background. The walls to this vase are thick and strong like their other vases. It is in good condition. This vase is signed by Margaret and Luther on the bottom. This piece can be dated before 1987 when Luther Gutierrez passed away. Margaret continues to make pottery. A fantastic piece to add to your collection.
