This is a vintage watercolor painting of a fish on a cream-colored paper. The fish is depicted in a realistic style, with a streamlined body and a slightly rounded head. It's a vibrant green color with darker green scales and a pale belly. The fish has large, expressive eyes and delicate fins. Around the fish, there are handwritten notes and labels in a delicate script. These appear to be scientific annotations, possibly detailing the species, location, and date of capture. There's also a faint pencil sketch of a geometric shape in the lower left corner. The overall impression is that of a scientific illustration or a naturalist's study.
