There are also tiny wheels. My feeling is that they probably once sat on some kind of a musical? Base and twirled around, lifting their arms and moving their heads. Date and provenance are a mystery, but they could be as late as 1950's.
Perhaps a collector will be able to tell me more... One doll is in near perfect antique/vintage condition, though whatever used to be in the base compartment is missing. The front of her silk skirt has some light yet visible holes - possible moth damage? One of the ribbons on her dress is slightly torn. Please look carefully at the photographs and do ask if you need to see more.
