French bronze style vintage sculpture, cast metal spelter bust of a young girl signed Miro

Cast metal bust of a young girl, probably spelter with an antiqued bronze finish. Base is marble, and the entire piece stands about 7 3/4" tall.

This looks as though it's signed L Miro? I haven't been able to track down any info about this maker or artist.

It's a lovely decorative piece, in any case. Very French country chateau style!
