Musical teapot in white porcelain with floral decoration

Old musical teapot in white porcelain with floral decoration and gold borders. Its originality: under the bottom of the teapot is a music box. Just go up the mechanism that is underneath (see photo) and trigger a slow and soft melody by lifting the teapot. When you rest the teapot the melody stops and leaves when you lift it again. Ingenious! Different rose décor on each side. Hard-to-find object that comes from japan.
