This is a vintage scientific illustration, likely from the late 19th or early 20th century, depicting facial wrinkles and body types. It's a double-page spread with two main sections. The left side is titled "Rides" (Wrinkles) and features a grid of black and white portraits of faces, each showcasing a different type of wrinkle. The wrinkles are labeled with French terms like "totale," "verticale et médiane," "temporelles," and so on. Each portrait is a close-up of a face, focusing on the wrinkles around the eyes, forehead, and mouth. Below the portraits is a key with corresponding letters and French descriptions of the wrinkle types. The right side is titled "Corpulence" (Body Types) and features a series of small portraits of men's faces and profiles, each illustrating a different body type or facial feature. These are labeled with letters and French terms like "Signe médian," "Largeur du front," and "Inclinaison de la bouche." The portraits show variations in facial width, nose shape, and overall body build. The overall style is detailed and anatomical, typical of scientific illustrations from that era. The images are monochrome and have a slightly grainy texture, adding to their vintage aesthetic. The text is in French and appears to be a detailed explanation of the different facial features and body types depicted.
