Not an antique piece, but in our experience, miniature pianos are difficult to come by so do please consider this one for use in your dollhouse, or room. In actuality an Austrian music box, this piece showcases very nice casting, good color and lovely details, however the music does not appear to be operable. 

Measures: 2 3/4" tall x 4 1/4" wide x 3 1/2" deep
