Dish Creil Montereau on foot

Big dish. Period 19th. The piece is in good condition, except for a 3mm gin barely visible on the ledge (see photo of the ledge) and a blow under the foot, totally invisible when the dish is laid. I didn't go any further research, and stayed more focused on other parts. It is a very decorative and modern dish for its time. It predates art deco, but for lack of another topic, I classified it in art deco.
