This is a classic designed plate by Santana and Adam Martinez.  Adam was the youngest son of Maria Martinez, and Santana painted Maria’s pottery in the 1940-50’s. The plate is stone polished and it is painted with a mountain and seed design.  It was fired a deep black coloration.  The plate is signed on the back in the clay, “Santana + Adam”. It is in excellent condition with no chips, cracks, restoration or repair.  Definitely a classic piece!
