This is a vintage illustration of three different types of fish, likely from a scientific or natural history publication. The background is a pale, mint green. The fish are depicted in a realistic style, with attention to detail in their scales, fins, and eyes. **Fish 1 (Top Left):** This fish is a golden-brown color with a slightly elongated body. It has reddish fins and a small, rounded mouth. Its scales are visible, and it appears to be swimming towards the left. **Fish 2 (Top Right):** This fish is a vibrant, deep red color. It has a more rounded body shape and prominent, flowing fins. Its scales are less visible than those of the first fish. **Fish 3 (Bottom):** This fish is a mottled brown and white color, resembling a leopard pattern. It has a more compact body shape and a distinct pattern of spots. Below the fish are labels in French: '1. Le Rouillé', '2. Le Cerise', '3. Le Leopard'. The illustration is labeled at the top with 'LONG-TSING-YU ou LES YEUX DE DRAGON. Espece des YA-TAN-YU ou OEUFS DE CANE.' and '22.' There is also text at the bottom left and right corners, likely indicating the origin or artist of the illustration.
