Korean War veterans have been called the “almost forgotten heroes” of the 20th century.

But many remember the people who served and sacrificed in this hard-fought war half a world away. This year marks the 50th anniversary of the armistice that ended hostilities there.

The U.S. Postal Service also has not forgotten. It will issue a new 37-cent stamp on July 27 honoring the Korean War Memorial in Washington. First-day ceremonies will be held at the memorial in the nation’s capital.

The Korean War Veterans Memorial was authorized by law in 1986. The memorial located on the National Mall, was dedicated by President Clinton and Kim Young Sam, president of South Korea, on July 27, 1995, the 42nd anniversary of the armistice.

The memorial displays 19 stainless steel statues depicting American troops in the Army, Marines, Navy and Air Force. They are shown marching in a wedge formation, as if on patrol.

The new stamp features a photo portraying the statues at the memorial shrouded in heavy snow. Photographer John W. Alli of Catonsville, Md., took the photo just before dawn during a heavy snowstorm in Washington in 1996. Alli specializes in photographing military aircraft and other military subjects.

First-day cancellations of the new Korean War Memorial stamp will be available from the Stamp Fulfillment Services by calling (800) STAMP-24.
