This is a vintage illustration of two fish, labeled 'LONG-TSING-YU ou LES YEUX DE DRAGON'. The background is a pale, muted green. The top fish (labeled '1') is a vibrant reddish-orange with darker markings along its back and sides. It has delicate, flowing fins and a small, round eye. The bottom fish (labeled '2') is a darker, mottled gray-green with a reddish hue around its head and tail. It has a more elongated body shape and similar delicate fins. Below the fish, there's text in a small font: '1. Le Robino, 2. Le Sombrun'. The illustration has a slightly aged, antique appearance, with subtle imperfections and a delicate watercolor style. The image is framed by a thin, pale yellow border.
