The servicemen interred in the Tomb of the Unknown Soldier are “Known But to God,” but they are every American s sons and brothers.  In honor of their sacrifices, a perpetual guard and the United States flag have stood sentinel over them since July 2, 1937.  Selected from the Army’s 3rd Infantry Regiment, the tomb guards are an elite group who stand sentinel around the clock, regardless of weather conditions.

In 2013, the U.S.P.S. added to the long-running U.S. flag series with the Flag for All Seasons issue.  Each format features four stamps picturing an American flag flying at the top of a pole.  The trees in the background display one of the four seasons on each stamp.  Three different printers supplied these stamps and the coil stamps can be identified by their perforations.  Order all six sets now with one easy order and save time and money.
