The image features a detailed sketch of a small rodent resting on crossbones. The color palette is monochromatic, composed of shades of grey with emphasis on shading to create depth and detail within the illustration. The mouse is centrally positioned on the page with its body aligned horizontally, while the bones beneath it form an "X" shape. The tip of the mouse's tail extends to the upper left side of the image, and the artist's signature, "G. Capelli," is located in the bottom right corner of the page.
