Reclaimed plaster moulded Classical scenes

Impressive antique chalk relief moulds depicting Classical Greek pastoral scenes.  One shows a Greek couple milking a goat, another a mother teaching a child to play a trumpet, and the third a scene with a huntress and her companion with a dog.  There is some yellowing to the chalk as well as some pitting and chips around the edges, commensurate with age. These are a beautiful and rare find.
