2001 US America Responds First Class Forever Stamps

In the aftermath of the September 11, 2001 terrorist attacks, the U.S. Postal Service issued a special semi-postal “Heroes of 2001” stamp to honor America’s courage and raise funds for families affected by the tragedy. This commemorative issue features the powerful, iconic image of three firefighters raising the American flag amid the rubble of the World Trade Center — a symbol of heroism, unity, and national resilience.

Each intact sheet contains 20 First Class stamps, making it not only a functional postage option but also a meaningful keepsake and historical collectible. A tribute to the bravery of first responders and the enduring spirit of the nation, this stamp sheet remains a poignant reminder of the heroes of 9/11.
