I picked this up at an estate sale. This is not rust, it is a stain of some sort. I found it in the garage. I have not found one like it. I think it is bronze and I have no idea on age. It does have the art nouveau vine. The angels pivot back and forth. 12” in diameter. Very cool piece. I would keep it, it trying not too! Any questions just ask. Thanks for looking at my stuff!
