These China Dolls are likely from the 1960's to 1970's or perhaps a little earlier. Though unmarked, the dolls appear to be handmade most likely from kits. The Mark Farmer Doll Company produced Doll Heads, Limbs, Clothing Patterns and instructions that looked like these dolls and some of their doll heads were unmarked. These favor their Jennie June dolls.
The dolls are not identical twins but certainly look enough like each other to be sisters. The doll heads certainly appear to be a selection from the many Jennie June style doll heads created by Mark Farmer. Their Pioneer style dresses are similar in style and fabric but with different trim.
Each doll has bloomers (pantaloons) and a long slip. The doll on the right within the first photo is in Excellent Condition with no flaws found. Her "sister" has a few issues with a repaired right ankle and some roughness on the top of her head. This same doll has some staining on her left shoulder that looks and feels like a little glue and there is some fading of the left sleeve of her dress.
Both dolls and their clothes are clean and well kept. No odors noted.
