It's likely a custom head mold or an altered mold.

I can't find any male dolls looking like that.

I am guessing it's a marionette not a doll.

^^^ good thought.

It is "strung" for use as a puppet?

all marionettes are not strung...many operate with sticks under the hands and feet.

So glad you said that maddielee, I kept looking at it trying to think who it reminded me of, you nailed it.
