Art Nouveau Belt Buckle

Can you help with this Art Nouveau Goddess Motif Belt Buckle.

Photos show my actual Goddess Motif Belt Buckle

I got this Art nouveau 2 piece goddess motif belt buckle, in bronze or brass, in a silent auction at a thrift store near my house.

I have had zero luck identifying the makers mark shown in the photo. I think it's a really cute buckle and would love to know more about it. It being art nouveau is just a guess!

I paid $10-15 for it. I couldn't get the makers mark to come up but it is a raised triangle inside a raised circle with the initials C&R.

The letters C and R are on opposite sides of the triangle with the & symbol in between.

Can anybody help a sister out?
