Antique Brass or Bronze Relief with a Very Detailed Asian Theme

I purchased a box lot an an auction recently and this was in one of the boxes. It is about 7 inches wide and 8 inches tall. It caught my eye because it is very highly detailed. It appears to have an Asian theme. On the back there are clips for attaching it to something. There is a small place that looks like it might be a signature or makers mark, but I can’t make it out. I’d appreciate any help identifying this piece. Thanks!
