Silver Cat Pin with Great Face

I don't buy much jewelry for the shop but occasionally something calls to me, like this silver cat pin, which looks like Mexican Taxco but appears to be unmarked. It's definitely silver though, and polished right up with no effort, and I think that face and eyebrows--or uni-brow, really-- are pretty hard to beat! 

2 1/2" wide and tall and in very good vintage condition.
