"Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift completion of their appointed rounds."
The history of America's postal service is filled with stories of those who risked their lives for the mail. The events of September and October 2001 have brought the courage and strength of these workers to light again.
"In the Line of Duty: Dangers, Disasters and Good Deeds" is an exhibition dedicated to America's postal workers. The exhibition was on view at the National Postal Museum from October 2003 to January 2007.
