This is for a lot of 3 used vintage dolls. I believe them to be Knickerbocker dolls. They are dressed as Amish people and includes a man, woman and child. The adults eyelids open and close, the child's does not. They are wearing blue and black cotton outfits. The woman is wearing a head scarf and the man has a hat. They measure about 7-1/2 inches tall and the child measures 5-1/2 inches They are plastic. Not sure if child is same brand? This item is cross listed so act fast!
