This is a round bowl by Margaret & Luther Gutierrez.  Margaret would make the pottery and her brother Luther would paint the designs using natural clay slips.  This bowl has a water serpent encircling the piece. Note how the body of the avanyu (water serpent) is made up of numerous different designs and a variety of colors.  All the various colors are from natural clay slips and this was a signature style of their work. The jar is signed on the bottom, “Margaret / Luther”.  It is in very good condition with no chips, cracks, restoration or repair.
