Most restrooms use simple labels such as MEN and WOMEN, but some are more creative. R. Robinson Rowe shared his collection in Word Ways in February 1977:

He added, “I was reminded of an incident at the treaty congress in San Francisco in 1952, when Japanese delegates unfamiliar with our language were briefed on the nomenclature of hotel restrooms: MEN would be a shorter word than WOMEN. An amused press reported their confusion and embarrassment when they were lodged in a posh hotel with facilities labelled GENTLEMEN and LADIES.”
