A detailed ballpoint pen drawing, rendered in blue ink, depicts the head and upper torso of a chimpanzee dressed in a military-style uniform. The drawing, executed with cross-hatching and fine lines to create texture and shading, shows the chimpanzee with distinct facial features, prominent ears, and textured fur. It wears a military cap adorned with a circular emblem at the front, and a collared jacket featuring multiple buttons down the front, lapels, and epaulets on the shoulders. A braided cord or aiguillette is visible over the left shoulder. The drawing occupies the majority of a white sheet of paper, which exhibits a spiral binding along its top edge, indicating it originates from a sketchbook or notebook. The paper is slightly angled, revealing a blurred, neutral-toned background surface, likely a table or floor. The specific location within the city of Jos, Nigeria, cannot be determined from the visual information presented in the image.
