Here's one that you would not see done again, and you might also expect to have been changed since 1945. Swastika motif in brickwork.
This is not as sinister as it might seem. Swastikas showed up as ornamental designs in quite a few things prior to World War Two, and they bore no association at all with the Nazi Party. In the west, they were associated with Indians, and were regarded as an Indian good luck symbol. Chances are that the architect of this Thermopolis, Wyoming building had that in mind, as Thermopolis is not far from the Wind River Reservation.
