This month’s Metro “Manners” poster portrays Tokyo’s ‘rudest’ train as part their continuing campaign to improve the deportment of their riders.
This month’s poster is a very “green” since its ideas and artwork are 100% recycled from previous “Manner” [sic.] posters as shown below.

More interesting is that a random guy named “NotInventedHere” psychically predicted the content of March’s poster!
Ive got one; How about don’t build small fucking trains and cram them with people. Bigger trains with more frequency equals less people getting crushed and sick from viruses. Yeah!
