2 coffee cups shape Limoges porcelain litron, blue oven SB

Here are 2 small coffee cups, in the shape of litron, and their sub-cup in limoges porcelain, gilding highlights on an oven blue background, inside the golden cups. Marked below " limoges france". I think of the 1930s-50s. Condition: together in very good condition, without chipping or repair, traces of water inside the cups, they will disappear with a sponge stroke, one as in the photos. Dimensions: cup: height: 5.5 cm, diameter: 5 cm, subcup: 11x2.5 cm. Neat package: about 1 kg.
