Pictured is an early yellow ware serving plate/platter available for sale.  The plate measures 10 1/4" in diameter,1 1/8" in height, & dates from 1880 - 1915 or slightly earlier.  It's in excellent condition with no nicks, damage or repairs, a very good example.  As seen, there is light discoloration to the underside.  If desired, one can assemble a decorative grouping set of 3 or 4 nested plates.  A yellow ware serving platter with great eye-appeal.....
