WASHINGTON -

The U.S. Postal Service dedicated the World War II Medal of Honor Forever stamps Sunday. The dedication is a tribute to the 464 American veterans who received the nation's highest military honor.

Two of the eight living World War II recipients were at the dedication which took place at the National World War II Memorial.

“Our challenge as a nation is to never forget the sacrifices all of these individuals made on our behalf,” said Postmaster General Patrick Donahoe in dedicating the stamps. “We hope these new Medal of Honor Forever stamps will provide everyone with one more way to preserve our veterans’ stories for future generations. I urge you to use these stamps and mail them around the nation and the world. Save them for your children and grandchildren. Let them serve as small reminders of the giant sacrifices made by the heroes of World War II.”

The set of 20 stamps can ordered at post offices nationwide, ebay or on the United States Postal Service's website.
