1. When the flag of the United States of America is displayed either horizontally or vertically against a wall, the union (stars) should be uppermost and to the flag’s own right (left, to the observer). When displayed in a window, the flag should be hung in the same way, with the union to the left, as viewed from the street.
No other flag or pennant should be placed above, or, if on the same level, to the right (the flag’s own 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. On such occassions, a church pennant may be flown above the flag.
