This is an amusing novelty doll head made by the German company Hertwig, depicting 2 children's heads - one with a happy face and the other sad. The happy faced child is wearing a pink mob cap and the sad child is wearing blue. The shoulder head has 4 sew holes, 1 on each side. It is marked 15 on the back.
The heads measure 2.25" tall. The base is 2.25" x 1.25".
Condition: There is a tiny chip on the upper lip of the unhappy face. Perhaps that is why so sad.
This would make for a delightful funny pin cushion top. It is a very uncommon form to see a 2 headed shoulder head like this.
