Orangutan Illustration - Historical Engraving of Primate Behavior #197128 (License: Personal Use)

This finely detailed wood engraving depicts an adult orangutan seated on a rough surface, mouth wide open in a loud call or yawn, with one arm raised and the other resting near its knee. The artist uses cross-hatching and stippling to render dense, shaggy fur, muscular limbs, and lifelike facial features, evoking both scientific accuracy and emotional intensity. Likely produced in the late 1800s, it reflects Victorian-era natural history illustration practices.
