This commemorative stamp from Antigua, issued in 1976, honors the 25th Anniversary of the United Nations Postal Administration (UNPA). The design features Hermes (Mercury), the messenger of the gods in classical mythology, symbolizing communication and the flow of messages. To the right, a symbolic image of people circling the globe emphasizes the UN’s mission of international unity and cooperation through postal services. With its ½ cent denomination, this stamp was part of a series marking "1976 Special Events." It stands as a tribute to the vital role of the UN in fostering global communication and harmony through its dedicated postal arm.
