This 2 centavos violet stamp was issued by Colombia in 1949 to commemorate the 75th anniversary of the Universal Postal Union (UPU), founded in 1874. The design, produced by Waterlow & Sons Ltd., London, features a detailed engraving of the orchid Odontoglossum crispum, one of Colombia’s most celebrated native flowers. The floral theme highlights Colombia’s rich biodiversity, while the UPU inscription underscores the importance of international postal cooperation. Printed in elegant violet shades, this issue is part of a larger commemorative set honoring both postal heritage and natural beauty.
