Cream Porcelain Heart Shaped Trinket Dish with Pink Calla Lily Signed

The bowl as well as the calla lily are made of porcelain and it looks like the porcelain calla lily is then glued to the dish. It is about 2 inches in height and 4 inches across (including the calla lily). the bowl is heart shaped and could be used as a trinket bowl on a dresser or part of decorations on a table. There is a pinpoint black spot on the bottom of the dish which is embedded in the pottery and there is no defect on the surface. There is a small cut in the calla lily where it curves downward (see pic) but there is glaze over it so it may have been done in the production process. There are "stretch marks" at the base of the calla lily but most seem to have glaze over them. There are a couple of rough spots at the edge of the calla lily and the rim of the bowl but again, there is glaze over them. There is a fleabite on the inside rim of the bowl at the point of the heart that does not have glaze over it. It is signed but I can not identify the artist.
