Rare Large Swan Lake Ballet Charger Ballerina

This is a large plate or charger, unmarked. It depicts the ballet Swan Lake, I believe. The center decoration consists of 5 swans with the wide rim depicting scenes of ballerinas. The plate is both hand painted and transfer decorated. Gilding. I have not been able to locate another one of these with a quick internet search. I believe it to be unique. 12.25" Condition - excellent. AB
