Double Decker Bus Designs

Some of the buses around town aren't the typical red that everyone is used to seeing. Many of the buses have come to be used as advertising, and with a lot of space to do so it seems to be pretty effective! The bus wraps need to be huge so I'm assuming they're printed in different pieces on a large wide format printer. Some of them are really eye catching because they're so different from the typical red. The typography is large to get the point across and so that they can be read from a distance. The popcorn one pictures below is the one I see most often for a brand that I hadn't heard of until coming to London.
