Foie gras serving

Foie gras service containing two dishes. A foie gras knife and a toast stand. Two trays with porcelain duck heads. The larger one is 25 cm long, 15 cm wide, and 10 cm high, with a white head. The smaller one is 18 cm long, 9 cm wide, and 5 cm high, with a cream, orange, and blue head. The larger one has a glass lid. A foie gras knife. A toast stand. Never used. There are very faint lines on the smaller duck; I don't know if they are cracks or part of the design, almost invisible (see photo).
