This is a vintage chromolithograph illustration of Great Barrier Reef fishes. The background is a pale yellow. Five different fish species are depicted, each with a number label. 1. A small, vibrant fish with vertical stripes of orange, blue, and white. 2. A larger, oval-shaped fish with a green and blue scale pattern. It has a prominent eye and a slightly open mouth. 3. A fish with a red head and body, covered in a scale pattern of red, green, and blue. It has a small, pointed mouth and a visible eye. 4. A larger fish with a similar scale pattern to the previous one, but with more prominent green and blue scales. It has a slightly open mouth and a visible eye. 5. A smaller fish with a pink and green scale pattern. It has a small, pointed mouth and a visible eye. Below the fish illustrations, there is text that reads "GREAT BARRIER REEF FISHES." At the very bottom, there is publisher information: "W. Saville-Kent, del et pinx." and "Ridder & Coe, lith, London, S.E." At the top right corner, there is a label that reads "CHROMO XV." The illustration is detailed and colorful, typical of chromolithographs from the late 19th or early 20th century.
