When displayed either horizontally or vertically against a wall, the union should be in the uppermost corner and to the flags own right, that is, to the observer's left. When displayed in a window, the flags should be displayed the same way, with the union or blue field to the left of the observer in the street.
No other flag or pennant should be placed above, or, if on the same level, to the right of the flag of the United States of America, except during church services conducted by naval chaplains at sea ... for personnel of the Navy ... when the church pennant may be flown above the flag. No person shall display the flag of the United Nations or any other national or international flag equal, above, or in a position of superior prominence or honor to, or in place of, the flag of the United States at any place within the United States or any Territory or possession thereof; provided, that nothing in his section shall make unlawful the continuance of the practice heretofore followed or displaying the flag of the United Nations in a position of superior prominence or honor, and other national flags in positions of equal prominence or honor, with that of the flag of the United States at the headquarters of the United Nations. The flag of the United States of America, when it is displayed with another flag against a wall from crossed staffs, should be on the right, the flag's own right, and its staff should be in front of the staff of the other flag.
When displayed outdoors with other flags, the position of honor for the U.S. flag is the U.S. flag's own right which is normally the extreme left position as the flags are most frequently viewed.
When the U.S. flag is displayed on a pole projecting from a building, the union of the flag should be placed at the peak of the staff unless the flag is at half staff. When suspended from a rope extending from a building on a pole, the flag should be hoisted out union first from the building.
When flags of two or more nations are displayed: in this circumstance, all the flags including the U.S. flag are to be flown from separate staffs of the same height. The flags should be of approximately equal size. International usage forbids the display of the flag of one nation above that of another nation in time of peace.
When other flags are flown from the same halyard: the U.S. flag should always be at the peak. When other flags are flown from adjacent staffs, the U.S. flag should be hoisted first and lowered last. No flag may above or to the right of the U.S. flag.
When flown at half staff: the U.S. flag should be first hoisted to the peak for a moment and then lowered to the half staff position. The flag should be raised to the peak again before it is lowered for the day.
The U.S. flag should form a distinctive feature at the ceremony of unveiling a statue or monument, but should never be used as the covering for the statue or the monument.
