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

Singapore · 1949 · 8c, 12c, 30c, 50c

This set of four stamps commemorates the 75th anniversary of the Universal Postal Union (UPU). The designs feature various modes of mail transport, including a mail train, a steamship, and an airplane, all superimposed over a globe to symbolize the UPU's international reach. Each stamp in the set has a different color and denomination.

Issued in 1949, this set was part of a British Commonwealth omnibus series celebrating the UPU's role in standardizing international postal services. Singapore, as a British Crown Colony at the time, participated in this widespread philatelic event.
