Not sure how they achieved this technique, but I have never seen another cup like it. The background of the cup has a matte gilt finish where as the raised decoration is brightly gilt. From the color of the porcelain body I believe that this cup is most likely french in origin. Though this example is unmarked, I've also seen another example that had a Limoges decorator's mark.
Good condition with no chips or cracks. The cup measures approximately 3 1/8 inches wide including the handle x 2 1/4 inches tall. The saucer measures approximately 4 1/2 inches wide. This is an antique and may have small in manufacture defects that do not affect the display of the piece.
