Together for London is a so-called 'passenger engagement campaign' that aims to stamp out annoying, anti-social behaviour on public transport such as playing loud music, talking loudly on mobile phones, being inconsiderate other passengers and so on.
It's hard to avoid the cutesy, Sanrio-inspired posters that are plastered all over London. Whether the campaign is effective or a waste of money is debatable but every time I see one I can't help thinking - Is that character meant to be Chinese? Check out the campaign website to see more:
