Capcom is holding a competition to find the very best imagery that the community can create that represents the tagline “Fight With Greatness”. Details can be found here –

The winning entries will receive a console, copy of the game and their art work printed and framed. They will also have a chance (pending Marvel and Capcom approval) of having their art featured in an official art book alongside other Marvel artists, ensuring fortune and glory. Presumably approval will be denied to anyone that depicts either Capcom or Marvel characters inappropriately, so whatever you do, don’t do that.
