The image is a vintage medical illustration, likely from an anatomical or therapeutic text. It depicts two extremely thin, skeletal figures and a box. **Figures:** Both figures are drawn in a very linear, almost ghostly style, emphasizing bones and minimal muscle mass. They appear to be facing each other. The figure on the left is slightly taller and has their hands positioned as if performing a percussive action on the back of the other figure. The figure on the right is standing with arms outstretched. **Box:** A square box is positioned to the right of the figures, with the hands of the figure on the right reaching towards it. The box appears to be a support or a surface for the figure to lean on. **Text:** Above the illustration, there is German text: '14. Stütz-gegenstehend a) Rückenhackung, b) Kreuzbein- und Lendenklopfung.' Below the image, it reads 'Fig. 16.' The overall style is reminiscent of early 20th-century medical illustrations, with a focus on anatomical representation and therapeutic techniques. The background is a pale yellow.
