Vintage Skeletons Diagram with Bones T-Shirt

Vintage darkly humourous 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. Here the lovers grace the front of a black boy's style t-shirt.
