These are on the ground floor of the hospital I visit sometimes. I guess it’s more interesting than pink and blue symbols to indicate which restroom is which.
The strange thing is, even more strange than the signs themselves, is that both restrooms are exactly the same. They are both handicapped equipped for single use only with a locked door. So I don’t know why you need to distinguish between a men’s room and a women’s room.
Still, interesting signs. I have a suspicion that they will not become generally popular.
