When the flag is displayed in any manner other than being flown from a staff, it should be displayed flat, whether indoors or out.
If displayed either horizontally or vertically against a wall, the union should be uppermost and to the flag’s own right; that is to the observer’s left.
When displayed in a window it should be suspended in the same way-that is, with the union to the left of the observer in the street.
When flags of states or cities, or pennants of societies, are flown on the same halyard with the flag of the United States, the flag of the United States should always be at the peak. When flown from adjacent staffs, the Stars and Stripes should be raised first and lowered last.
