Hippopotamus Illustration - Classic Scientific Line Art Drawing #135081 (License: Personal Use)

This high-detail scientific-style line drawing captures a hippopotamus in a natural standing pose, with meticulous attention to skin folds, muscular structure, and facial features like small ears, eyes, and broad snout. The artist uses dense cross-hatching and stippling to convey volume, weight, and texture, evoking classic zoological illustration techniques from the 19th and early 20th centuries. Small ground details and a subtle watermark suggest its origin as vintage clip art.
