The paper is filled with intricate details, including the various parts of the brain, such as the cerebrum, cerebellum, and cerebrospinal cord, as well as the various organs and structures of the body. The drawing is done in black ink on a white background, and the paper is slightly crumpled, giving it a worn and aged look.
