This is a gorgeous Rudolstadt porcelain oyster plate. Its dimensions are approximately 10 x 7 1/2 inches. It is in excellent condition, with no chips, cracks, repairs, hairlines, etc. The colors are vibrant. A very similar plate can be seen on page 128 of Jeffrey Snyder's Collecting Oyster Plates and shows a value of $495 to $545.
