Although Arcadia Ceramics, a California pottery company from the 1940s-50s, is most famous for their miniature salt and pepper shakers, they also produced many nice larger sets.

Many of their other sets are animals that can be found interchangeably on different bases or trays.

This set is a swan tray that has been found with both flowers and swanlings.
