Chinese Porcelain 'Piano Baby'? No Signature: Age? Purpose?

She's about 8 inches long, right fingers to toes, and ~4¾ inches high. Her head & body have been slip-cast separately; probably the green medallion as well, but I cannot see enough to confirm that. Her weight is just shy of 400 grams. ('Her' is assumed due to the pink garment; a dangerous viewpoint, I know.)

Several details are worth pointing out; her hair, that's been shaven away, is done by the finest stippling I've ever seen...it has texture! The blush on her cheeks is also a very fine matte finish. Then there's that medallion...not enough detail to say what it might be.

Her head & facial features are exquisite anatomically and in symmetry; the position of the pupils perfectly creates a gaze focused at infinity. Whoever crafted this child was masterful in artistic expression where it mattered.

I cannot find another example of an Asian Piano Baby...perhaps she's something else. She's smaller than most of them.

Some of you will be of great help about her, I know...Thanks!

Very cute!

 

The mark on the one on ebay is post war, probably 1970's or so from the looks, can't help otherwise, sorry.
