This is why I'm glad to now have a camera phone. I spotted this magical mistake of advertising, where I presume the last panel of the poster was either never applied to the bus or somehow came off, and didn't realise it was an error at first, so well does it line up together. I think the section on the right is from one of the MTA's own ads.

Is it me, or does the movie look much more interesting this way?
