Circa 1936-1951: The plate is the backbone of a potteries line, and it is here on the Century shape plate that the simple, scalloped edges on all four corners harken to the art deco era. Dipped in the mauve blue glaze for the Riviera line, this 7" salad plate is actually harder to find than one might think and after the extremely elusive 10" dinner plate will be the next hardest to find to complete the Riviera place setting. Measures 7 1/8" wide.
