Postcards is an outdoor sculpture in St. George, Staten Island, New York City, United States. Built in 2004, it is a permanent memorial honoring the 274 Staten Island residents killed in the September 11 attacks of 2001 and in the 1993 World Trade Center bombing. The dead include many who worked at the World Trade Center, police and firefighters who joined the rescue effort and were killed when the towers collapsed, and one passenger on United Airlines Flight 93, who died in the crash in Shanksville, Pennsylvania. One individual who was killed in the 1993 World Trade Center bombing is also represented.

St. George is a neighborhood on the northeastern tip of Staten Island in New York City, along the waterfront where the Kill Van Kull enters Upper New York Bay.

The St. George Terminal, serving the Staten Island Ferry and the Staten Island Railway, is also located here. St. George is bordered on the south by the neighborhood of Tompkinsville and on the west by the neighborhood of New Brighton.
