Man with Open Mouth
Unknown maker, French

Is this man's open-mouthed expression one of agony or ecstasy, his cry one of pain or joy or rage? Probably none of the above; most likely, this image was made as a scientific record of a man with deformed teeth and diseased gums, thus making it an example of an early photograph created as a medical document.
