The image is a plate featuring a collection of prehistoric stone tools, specifically arrowheads and other shaped stone fragments. The plate is labeled 'PLATE 128.' The tools are rendered in a blue-toned, illustrative style, resembling a technical drawing or archaeological documentation. Each tool is numbered for identification. The tools vary in shape and size, ranging from triangular points to more complex notched and stemmed forms. Some are simple flakes, while others appear to be more deliberately crafted projectile points. The arrangement is dense, with the tools overlapping and filling the entire plate. The background is a pale yellow, providing contrast to the blue illustrations. The overall impression is that of a catalog or reference sheet for archaeological artifacts.
