Circa 1938-1948: The vintage Riviera pottery oatmeal bowl was added to the line right before Christmas in 1938. A great piece of pottery, surprisingly large for the otherwise petite Riviera line, the oatmeal bowl is the perfect size for many uses and is a delight to see dipped in your favorite color. The bright and sunny Harlequin yellow glaze was the yellow used in the Riviera line and it's delightful on the harder to find oatmeal bowl shape. Without damage or use. Measures 6 1/4" x 2".
