Postage stamps can tell layered stories — about their place of origin, about their sender, about world events — you just need to get them and use them. Let’s use postage stamps to revive International Letter Writing Week.

Tomorrow, October 9, will be World Post Day’s 54th birthday. Although the United Nations was created in 1945, the Universal Postal Union (UPU), now part of the UN, was established as an independent body in 1874, and is probably the oldest existing intergovernmental organization.
