This is a vintage x-ray image of a lizard skeleton. The lizard is depicted in a curled position, with its head to the right and tail curving around its body. The skeleton is clearly visible, showing the delicate bones of the skull, spine, ribs, limbs, and tail. The image has a monochromatic, sepia-toned appearance, typical of early x-ray photography. The background is a light, off-white color. At the bottom of the image, the text 'Grüne Eidechse' is visible, which translates to 'Green Lizard' in German. At the bottom left corner, the text 'Eder u. Valenta' is visible, and at the bottom right corner, the text 'Versuche mit Röntgen-Strahlen' is visible, which translates to 'Experiments with X-rays'.
