WASHINGTON (AP) — The U.S. Postal Service is releasing two new stamps paying tribute to the 150th anniversary of the Civil War, specifically the Battle of New Orleans and the Battle of Antietam.

The “Civil War: 1862″ stamps were released Tuesday. The stamps mark the first significant achievement of the U.S. Navy in the war during the Battle of New Orleans and the bloodiest day of the conflict at Antietam.

The New Orleans stamp is a reproduction of an 1862 color lithograph titled “The Splendid Naval Triumph on the Mississippi, April 24th, 1862.” The Antietam stamp is a reproduction of an 1887 painting by Thure de Thulstrup.

Postal Service Vice President Dean Granholm says the stamps help Americans pause and remember a period of history that had a lasting effect on the nation.
