I spotted these beautiful early 19th century skull statuettes in a back alley shop in Paris's Saint-Germain-des-Prés neighborhood. The smaller one, an anatomical model, is just a bit bigger than a shotglass. Unfortunately, they're made from ivory which was a popular medium at the time. Of course, the acquisition of ivory has tragically devastated populations of elephants, rhinos hippos, and other animals that produce the material. Click the images for bigger photos.
