Church Street Post Office mail sack
In the twenty-first century the United States Postal Service still uses mail sacks, but the materials have evolved from canvas and leather to light-weight plastic. This express mail sack was collected from the Church Street Station post office in New York City as an example of an everyday object tied to a larger historic event.
The Church Street Station served the World Trade Center postal routes, and on September 11, 2001, an entire ZIP code was destroyed by terrorist attacks. Church Street Station reopened on July 31, 2004. It underwent extensive repairs, including the replacement of more than eight hundred windows. New lighting and furniture were installed, but otherwise few changes were made to the historic building’s marble lobby.
