In recognition of Flag Day this Thursday, here's a few facts about America's flag:
• Congress approved the official U.S. flag with 13 stars and 13 stripes on June 14, 1777.
• The star representing Missouri was officially added on July 4, 1882.
• The flag has had 27 official versions. The arrangement of the stars varied according to flag makers' preferences until 1912, when President Taft signed an executive order that specified how the stars should be arranged.
• The red on the flag represents valor and bravery; the white, purity and innocence; and the blue, vigilance, perseverance and justice.
• According to the Federal Flag Code, the flag isn't supposed to be used for advertising purposes, on clothing or costumes, on home décor like bedding or curtains, or on products such as napkins, which have a temporary use and are then discarded.
• Constituents can contact their senators or representative to purchase a flag that has been flown over the U.S. Capitol.
