City of Heroes is running a contest from now until until 11:59pm CT on Monday, January 24, 2011 to design a billboard. You can get your artwork in-game by designing a billboard for Paragon City. The COH team has explained a great way to find inspiration:

Well, imagine that a new business is setting up shop in Paragon City and the Rogue Isles, and that you've been hired to create their signage. Your task is to invent a brand-new ad campaign, displayed on a billboard, to promote a product, retailer, restaurant chain, in-lore political candidate, or service of your own devising (or based on lore) that you've always wanted to see in the game!

There will be three winners chosen and each one is slated to recieve an awesome list of prizes! So head on over to the City of Heroes official page for full details on how to submit your entries!
