Vintage Skeletons Diagram with Numbered Bones Poster

Vintage darkly humorous black and white image of a skeleton couple, one facing front, the other facing back, seemingly holding hands and looking into each other's eyes, as though they are about to begin a dance. Each anatomically correct skeleton is diagrammed with numbered bones, at one time possibly used in a science laboratory of old, or a classroom receiving a lesson in the human skeletal system. And here you have a poster of this image, perfect for displaying in said lab or class!
