These are photos of the toilet in one of the Russian cities.
Here is the sign “The corrector of the stream”.
And here “Clean up your dump!” . It’s a male part of the restroom.
And this one is for ladies. Note the gymnastic apparatus hanging from the ceilings. Their purpose is to help women using this model of the toilet. And above the gas mask there is a sign “Got a relief? Freshen up now!”
