The image is a vintage illustration of a koala clinging to a tree branch. The koala is depicted in a full-body view, showcasing its fluffy, grey-brown fur. Its ears are rounded and fluffy, and its nose is pink. The koala is gripping the branch with its sharp claws, and its body is positioned in a slightly hunched posture. The tree branch is textured and appears to be made of bark. The background is a soft, off-white color, which helps to highlight the koala and the branch. The illustration is detailed and realistic, with attention paid to the texture of the fur and the bark. The style of the illustration is reminiscent of 19th-century natural history illustrations. The text at the bottom of the image reads 'Phascolarctos cinereus', which is the scientific name for the koala. There is also some smaller text indicating the artist and publisher.
