The image is a detailed illustration of a prehistoric stone tool, specifically a hand axe. It's rendered in a style reminiscent of 19th-century archaeological drawings, with delicate watercolor washes and precise linework. The hand axe is a triangular shape, with a broad base and a pointed tip. The surface is a mottled mix of light beige, reddish-brown, and darker brown hues, suggesting the natural coloration of the flint from which it's made. The illustration highlights the flaking patterns created during the tool's manufacture. There's a distinct band of dark, almost black, material near the top of the tool, possibly indicating a different layer or composition within the flint. The illustration is set against a pale yellow background. In the upper right corner, the number '167' is handwritten. Below the image, there's a caption in a delicate script that reads 'Feb. 1. 1865 - Published by J.W. Soweby, London.'
