This is a flat top seed bowl by Grace Medicine Flower.  It is from 1973.  She remains renowned for her creative pottery.  The bowl is fully polished.  On the top, it is etched with a water serpent (avanyu), which encircles the opening.  On the side, there is another avanyu that encircles most of the piece. Do you see the little “Medicine Flower” that is near the tail of the avanyu?  The jar is signed on the bottom in the clay, “Grace Medicine Flower”.  It is in excellent condition with no chips, cracks, restoration, or repair.
