The U.S. Postal Service is issuing a special stamp commemorating the 150th anniversary of the Battle of Gettysburg.
A ceremony to unveil the stamp will be held at Gettysburg National Military Park on Thursday, the same day that the Postal Service says the stamp will go on sale nationwide.
The stamp depicts a painted image of a chaotic battlefield, with smoke rising from fired rifles.
The three-day battle in July 1863 was the largest of the Civil War. It is considered the war's pivotal moment after Northern forces turned away a Confederate advance.
The Postal Service has been commemorating the 150th anniversary of the Civil War with a series of stamps.
A stamp commemorating the Battle of Vicksburg will also be unveiled next week in Mississippi.
