Yep, according to the US Flag Code:

When 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.

TBF, it does have different instructions about how to display the flag outdoors, hard to tell from this perspective if it was actually hung properly.

Even when hanging the flag vertically, this is the correct orientation, with the stars in the upper left.

Interesting, do you have photos?

The rim is an uneven thickness and has some jagged spots which made me think it might have been cast by hand.
