This is the first in a series of three issues (C42-44) celebrating the 75th anniversary of the formation of the Universal Postal Union. The design features the Post Office Department Building.

Before the formation of the Universal Postal Union, countries had to have postal treaties with each nation they wanted to carry international mail to and from. That meant a letter had to have stamps from each country it would pass through on the way to its final destination. The Universal Postal Union was formed in 1874 to simplify the process.
