Is this doll authentic?

I saw this doll online and I am wondering if she is authentic or a fake? I think her marking is Heinrich Handwerck, but I have never seen a Handwerck with a fully painted face before. (No glass eyes.) She has bisque head, hands & feet. Her body looks like white cloth. Her wig is glued on. Her height is 20". Can anybody give me any information? Thank you.
