These Depression era divided grill plates are in the Normandie or Bouquet and Lattice pattern, produced in the 1930s by Federal Glass. The iridescent marigold Carnival style color is called Sunburst. Each of the three plates measures 11 inches diameter. One has a thin, flat, sliver flake on the underside. The other two are in excellent condition. Price is for the set of three plates (I have 2 sets available for a total of 6 plates).
