Photograph of a doctor using part of an early model X-ray machine on a male patient, [s.d.]. The young male patient can be seen, center, fully clothed in a suit, white shirt, and striped tie, standing on a stool, above the doctor, leaning his abdomen against a photographic plate that will be exposed to X-rays. The doctor stands, in profile, at left, wearing a dark suit. Four book shelves stand attached to the wall, covered with rows of books.
