Believe it or not these are officially licensed and an actual part of the Hellboy 2 marketing campaign.
To be more specific they are part of the UK campaign for the movie, which doesn't come out until sometime in August over there. So around that time these will be released "virally" outside of the Cubeecraft site. Exactly how that's going to go down I'm not sure. The versions I've seen previously have the Hellboy logo branded on them, so those will possibly make another appearance when they're released officially, we'll just have to wait and see.
