Its a very, very old weathered doll made it looked like upon 'sort of' closer inspection, either 1940's sort of thick plastic or something to that effect.
Yes, it can creep you out some. Not so much the doll, as the thinking of the person who owned it.
My creepy thing was finding a plastic full size human skull in the hollow of a tree at a CW battlefield about I guess a year ago. I can remember the events, not the year it occurred in. I had to ask the vet how old my black cat was yesterday. Go figure.
