A new exhibit at the New York Transit Museum's annex in Grand Central Terminal is taking aim at the seat-hogging practice of "manspreading" and other subway faux pas.
It's called "Transit Etiquette or: How I Learned to Stop Spitting and Step Aside in 25 Languages."
The gallery features recent and vintage campaign courtesy posters from metro systems around the world.
They address just about every kind of bad commuter behavior-- from spitting to littering to blocking the door.
The exhibit runs through July 10.
