Even in this ultra-modern age of online banner ads, sponsored tweets and social networking “commercial takeovers” some of the best advertising space is still the old school, low-fi posters you see stuck to the side of buses.

That’s particularly true in London, where the buses crawl at a snail’s pace through the traffic-clogged streets. Stick your ad on the side of a double-decker in the UK’s capital and you’re sure of some serious exposure.

So, the prize up for grabs at bigbuschallenge.com should appeal to anybody with something to show off to the world.

If you’re a business just starting out, this kind of coverage is something you can only dream of, but CBS Outdoor are willing to provide a £200k ad campaign to the winning design for absolutely nothing.

You’ve got until the 24th of this month to get your design in, so get creative and get on the bus.
