Early Anatomical Half Head Model
This is the quality and style of item I like to add to my own collection. I do have a matching example in my collection already so this one is for sale. It is unsigned buy attributed to Wilh. Schluter / Naturwissenschaftliches / Halle a Saale. The head is Gesso, papier mâché and plaster. The scale is life-size. It stands on a turned wood and brass weighted base. It's difficult to tell but there may have been some restoration on this early model... $2600
