Vintage 1940s Siam Sterling Silver Male Dancer Ramasoon Thunder God Pin Brooch

This is quite and old piece and it's sterling silver - as such, it has a nice patina. It can be polished up easily if you prefer, but many buyers like to keep the patina so I leave it up to you. Please review the photos - there's a small hole on the bottom right of the piece that may have had something dangling at one point in time. Through my research, I wasn't able to find a matching piece with anything dangling, so I'm not sure.
