Singapore 75th Anniversary of the Universal Postal Union (UPU)

Singapore · 1949 · 8c, 12c, 25c, 50c

This set of four stamps commemorates the 75th anniversary of the Universal Postal Union. The designs feature various modes of mail transport, including a mail steamer, a postal train, a mail plane, and a modern airliner, all set against a backdrop of a globe, symbolizing the UPU's international reach.

Issued in 1949 as part of a British Commonwealth omnibus series, this set marked a significant global milestone for postal cooperation in the post-war era. It was one of the first commemorative sets issued by Singapore after it became a separate Crown Colony in 1946.
