This is a vintage chromolithograph illustration of various coral species found in the Great Barrier Reef. The image is a detailed chart showcasing different types of coral, each labeled with a number. The corals are depicted in vibrant colors, including shades of red, green, blue, and brown. They exhibit a variety of shapes and textures, from branching structures to rounded formations and intricate patterns. The illustration is reminiscent of a scientific or botanical chart, with a grid-like layout and precise detailing. The overall aesthetic is that of a classic natural history illustration, likely from the 19th or early 20th century. The background is a pale cream color, providing a neutral backdrop for the colorful coral specimens. The illustration is labeled 'GREAT BARRIER REEF CORALS' at the bottom, and includes the printer's information 'W. Saville, del. et sc. nec.' and 'Riddle & Couchman, Imp. London. S.E.' along the bottom border. The top right corner is labeled 'CHROMO V'.
