These are "Piano babies" is a collector's term for small, often bisque porcelain figurines, typically depicting babies or young children, that were popular decorative items in the late 19th and early 20th centuries.
Here's more about them:
Original Purpose: In the Victorian era, well-decorated homes often draped a shawl or scarf over the piano to protect it from dust and add a decorative touch. Piano babies were originally designed to sit on top of the piano, acting as weights to hold these shawls in place.
Origin: Most original piano babies were manufactured in Germany by companies like Gebrüder Heubach, known for their expressive and realistic features.
Materials and Poses: They were commonly made from bisque porcelain, which has a matte finish, and came in a variety of poses, including sitting, crawling, or even playing with their toes.
Collectability: While their popularity peaked in the early 20th century and again saw a resurgence in the 1980s and 90s, they remain collectibles.
