This is a classic bowl by Santana and Adam Martinez.  Adam was the youngest son of Maria Martinez, and Santana (his wife) painted Maria’s pottery in the 1940-50s.  The entire surface of this piece is fully polished.  The feather design was then painted around the shoulder of the bowl.  The piece was traditionally fired to dark black coloration.  It is signed on the bottom in the clay, “Santana + Adam”. It is in excellent condition with no chips, cracks, restoration, or repair.  Definitely a classic piece!
