Mary Lewis was a daughter of noted potter Lucy M. Lewis.  She was never as prolific as her sisters Emma, Dolores, and Carmel. The plate has a single large Mimbres-inspired turtle as the design.  The Mimbres pottery designs of the 1100s began to be used as imagery on Acoma pottery in the 1960s.  The rim of the plate is “corrugated” or impressed with a triangular design and painted with red clay.  It is signed on the back, “Mary D. Lewis”.  It is in excellent condition with no chips, cracks, restoration, or repair.
