This is a vintage x-ray photograph featuring three fish. The fish appear as ghostly, translucent skeletons against a dark background. The x-ray reveals the intricate bone structure of the fish, including their spines, ribs, and skulls. The fish are positioned diagonally across the frame, with one at the top, one in the middle, and one at the bottom. The image has a scientific and historical quality, reminiscent of early experiments with x-ray technology. The text at the bottom reads 'Zwei Goldfische und ein Seefisch (Christiceps argentatus)' which translates to 'Two Goldfish and a Sea Fish (Christiceps argentatus)'.
