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 back towards 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, there is text that reads 'Grüne Eidechse' (German for 'Green Lizard'). At the bottom left and right corners, there are additional inscriptions in German, likely indicating the source or method of the image ('Eder u. Valenta' and 'Versuche mit Röntgen-Strahlen' - 'Experiments with X-rays'). The overall aesthetic is scientific and historical, reminiscent of early anatomical studies.
