I have seen these horses done with one of two bases...either a wood music-box base, or a brass rectangular base.
This particular one is unusual in that it has different designs on the romance and non-romance sides.
These pieces are retired, I'm pretty sure IGI isn't making any of them anymore.
I am not sure overall what this piece cost when new, though this one does still have a pricetag (from a Hallmark store)
on it, for $61.
