I got these dolls from a button seller at a flea market. I haven't been able to find any information on this type of doll in either doll collecting books or internet searches.
The dolls are built on ball-head pins. I think they are glass, but it is hard to do the "cheek test" for glass with them because I don't want to risk damaging the delicate painting or mussing the clothing. (You know the "cheek test", right? If you put an object that is glass, stone, or shell up to your cheek, it feels cold. Plastic will feel more like room temperature.)
The heads are the heads of the pins, arms and legs are thin coated wire, and the tiny clothing seams are hand sewn using fabrics that appear to be cottons, including voiles, and wools or felt. There is a little circle of glue on the back of each one. They stand by pushing the end of the pins into a softish base. The dolls are quite detailed for such tiny objects.
If anyone has any information on these, I would love to know more about them.
