This vibrant trio of Guyanese definitive stamps celebrates the rich aquatic life of South America’s waterways. Issued in the 1960s, the set features three freshwater species—Sunfish (1¢), Pirai (2¢), and Lukunani (3¢)—each depicted in fine detail against colorful backgrounds. The “Postage and Revenue” inscription marks them as part of a standard definitive series used for both postal and fiscal purposes. These stamps capture Guyana’s ecological diversity and artistic presentation of native fauna, making them a favorite among collectors of wildlife and tropical themes.
