Does anyone have any ideas about this plate, which I received from my grandmother in law? There is the name “Josephine” written under the woman. Given this, and a search on the internet, I’m assuming it’s Empress Josephine:

I’ve been doing some searching, but haven’t found an exact copy. Here is the closest I’ve found:

If you scroll through the close ups here, you’ll see that the picture of Josephine on this plate is nearly an match, including her name printed “Josephine” under it.

There aren’t any other markings on the plate. Nothing on the back. There are 16 holes around the outside of the plate.
