Papua New Guinea 1971 Birds of Prey and Native Birds Postage Stamp Set

This items consists of three vertically oriented postage stamps from Papua New Guinea, specifically from the definitive series issued around 1971. The stamps feature highly detailed profile illustrations of native bird species: the 'Kokomo' (Blyth's Hornbill) on a 7c teal background, the 'Muruk' (Southern Cassowary) on a 10c gold background, and the 'Tarangau' (Papuan Eagle) on a 30c light blue background. Each stamp measures approximately 25mm x 30mm and is printed on white paper with visible perforations around all edges. The illustrations are rendered with fine detail, showcasing realistic textures in the feathers, beaks, and wattles, indicating high-quality lithographic or offset printing. The denominational numerals are placed in the upper corners, while the country name 'Papua New Guinea' is printed in a bold white serif font within a black horizontal bar at the bottom. Scientific names like 'Aceros plicatus', 'Casuarius casuarius', and 'Harpyopsis novaeguineae' are included in small italicized text. Condition appears excellent with clean, white perforations, no visible creasing, and vibrant, unfaded colors, though they appear to be housed behind a clear protective plastic sleeve in an album. This set represents a transition period in Papua New Guinean postal history shortly before independence.
