The image shows two panels, side-by-side, depicting a sequence of a diver performing a backward spring outwards and turning inwards with a somersault. **Panel 4:** Shows a series of four figures illustrating the dive. The first figure is on a diving board, poised to jump. The second figure is mid-air, arching backward. The third figure is fully inverted, performing a somersault. The fourth and final figure is entering the water vertically. **Panel 5:** Mirrors Panel 4, showing the same sequence of a diver performing the same dive. The diver is shown in the same positions as in Panel 4, but with slightly different angles and details. Both panels have a simple, illustrative style with black lines on a light background. The water is depicted with horizontal lines to indicate its surface. Below each panel is a caption describing the dive: "4. Backward spring outwards and turning inwards with somersault." and "5. Backward spring outwards and turning inwards with 1½ somersault." The overall impression is that of a vintage instructional diagram for diving techniques.
