This vintage Fiesta compartment grill plate was produced by the Homer Laughlin China Company.  Fiesta's original shapes and its glazes were designed by Frederick Hurten Rhead, Homer Laughlin's art director from 1927-1942. This plate measures 10.5" in diameter by about 3/4" off a flat surface.  It has three divided sections and is glazed in a cobalt blue glaze, which is rich and vibrant in color.  This is an original plate, not a later issue. It is unmarked, but guaranteed to be vintage Fiesta ware. It is in remarkably good condition with just a couple of no harm surface scratches and the usual underside stilt marks.
