caption: The image shows a black and white engraving of a chimpanzee sitting on a rock, with text at the top and bottom of the image. The chimpanzee is depicted in a meditative pose, with its hands resting on its lap and its eyes closed. Its fur is shaded in a light brown color, and its face is framed by a long, thin beard. Its hands are clasped together in front of its chest, and it has a peaceful expression on its face.
