The image is a vintage illustration depicting a sequence of a person performing a forward somersault dive. The illustration is done in a simple, line-drawing style with shading. The sequence begins with two figures on a diving board, one running and the other poised to dive. A dotted line traces the arc of the diver's trajectory through the air. The diver is shown in several positions along this arc, illustrating the stages of the somersault. The diver is depicted in a tucked position, with knees drawn towards the chest, and arms wrapped around the legs. The final position shows the diver entering the water vertically. Below the sequence, there's a depiction of the water surface with some simple wave-like lines. At the very bottom, the text reads "10. Flying somersault forwards."
