The image is a close-up of a wooden surface with a black and white speckled pattern. On the surface, there are three stick figures drawn in black ink. The figures are arranged in a triangular formation, with the first figure on the left, the second figure in the middle, and the third figure at the bottom. Above the figures, there is a line drawing of a wave-like shape. The words "screw heads" are written above the figures. The image appears to be a diagram or illustration that shows how to draw a screw head.
