John Walkenbach gave me a heads up about this image, which has been puzzling visitors to his blog. Is it real or fake? His readers have already figured out that the message on the front of the bus means "cross on the zebra crossing" (or something to that effect) in Portuguese. In other words, it's warning people not to jaywalk, or they'll end up hit by a bus. It's hard to tell with such a low-resolution image whether or not it's real, but my hunch would be that it is real. I don't see any obvious signs of photoshopping. It reminds me of the 'Air Santa' image that was circulating around a few years ago (which seems a bit more fake to me).
