Ho hum, much ado about nothing.
Several years ago I visited Seoul Korea on business.
Every inch of the hotel elevator’s interior was embossed with small “Swastika’s”!
Apparently an old time good luck symbol, appropriate to an elevator in a not quite first rate technology country.
BTW, this was during the “Asian Games” and again two years later during the Olympics.
I bet the elevator has not been remodeled.
Oh, and not only did the Navaho use a version, so did some of our own military up to early W.W. II.
