This is a vintage illustration of a squirrel skeleton. The image is sepia-toned and appears to be from an old scientific or anatomical text. The main focus is a full skeletal depiction of a squirrel in a seated position. The bones are detailed, showing the ribcage, spine, limbs, and skull. The skull is particularly prominent, with visible eye sockets and teeth. To the left of the full skeleton are three separate illustrations of squirrel skulls, each shown from a different angle. These provide a closer look at the skull's structure. The background is a warm, off-white color, and the entire image is framed by a thin, dark border. The style is reminiscent of 19th-century scientific illustrations, with a focus on accuracy and detail. There is a small number 'VII' in the upper right corner.
