This is a vintage-style illustration of a bat perched on a tree. The bat is a warm brown color with large, pointed ears and outstretched wings. It appears to be hanging upside down from a branch. The tree trunk is light brown and textured, with a variety of fungi growing on its surface. A few green leaves and a branch are visible in the lower left corner of the image. The illustration is detailed and appears to be a scientific or natural history illustration. The text 'MOLOSSUS AUSTRALIS, Gray' is written above the illustration. The illustration is on a white background.
