Stamped copper plate

[TxTim]

I found this in a WW1 dump area.
It's about 6" diameter and stamped on copper about 1/16" thick.
No ID marks or writing at all. Any ideas

Looks like a decorative rosette of some sort.

Decorations that go on ceilings..... My grandmothers ceilings were tin 2ftx2ft with something like the medallion for decoration and to hold it up....I know there were at least 6 to 10 coats of paint on it!!! LOL

It looks like Art Nouveau , wich started in the 1890's . Maybe it's the lid to a ladies powder box from a vanity set ?
