The image is a vintage illustration depicting a diver performing a backward spring outwards and turning inwards with a header. The illustration shows a series of four sequential positions of the diver in mid-air, starting from the diving board and descending towards the water. The diver is shown in a curved, arched position, with their body gradually rotating inwards. The illustration is done in a simple, line-drawing style, with minimal shading. The background is a plain, off-white color. Below the illustration is a caption that reads "3. Backward spring outwards and turning inwards with header."
