Cresencia Tafoya is the mother of noted potters Harriet Tafoya and Annie Baca. This is a classic piece of her black-on-black pottery.  The bowl is oval in shape and has a sharp shoulder. The design is an avanyu (water serpent) encircling the piece.  Note the cloud and rain designs extending downward. The piece is in excellent condition with no chips, cracks, restoration or repair.  It is signed on the bottom, “Cresencia”.
