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 steamship, a mail train, and an airplane, all superimposed over a globe to symbolize the UPU's international reach. The portrait of King George VI is included in the upper right corner of each stamp.

Issued in 1949, this set was part of a British Commonwealth omnibus series celebrating the UPU's role in standardizing international postal services. It reflects the post-war era's focus on global cooperation and rebuilding international communication networks.
