What is the incorrect way to display the United States Flag according to standards?

The correct understanding of displaying the United States Flag is that the "union" (the blue field with stars) should always be positioned in the observer's upper left when the flag is displayed horizontally or vertically against a wall. This placement ensures that the flag is seen in the proper orientation, symbolizing respect and honor.

Displaying the flag with the union on the flag's own right, indicated in the second option, is incorrect. This position would mean that the union would appear on the left side when facing the flag, which is not acceptable according to flag etiquette. Likewise, while displaying the flag flat on a surface, it is important to maintain the union's position at the top, as noted in the third option. Additionally, the flag should indeed be flown at half-staff to honor fallen service members on Memorial Day, which is a recognized practice.

Therefore, the option indicating the union to the observer's upper left is not the incorrect presentation but the standard practice that aligns with flag etiquette. It is crucial to adhere to these established guidelines to show proper respect for the flag and what it represents.
