Issued by Antigua in 1974, this ½-cent commemorative marks the 100th Anniversary of the Universal Postal Union (1874–1974). The design beautifully contrasts centuries of mail delivery: a 19th-century English postman, an early mail coach from 1784, and a modern postal helicopter, symbolizing the progress of global communication. The vibrant artwork highlights Antigua’s participation in worldwide postal modernization and remains a popular thematic item for UPU, transport, and postal history collectors. A fine representative of mid-20th-century Commonwealth commemoratives.
