I remember one fine April Fools someone on the CoH forums posted a nicely done mockup of an expansion info sheet for a cosmic-level CoH expansion. I think this was shortly after CoV's release, but I could be wrong. It was primarily yellow/gold colored and titled something like 'Galaxy of Heroes' or 'Universe of Heroes'.
It was an image, and I think there might have been some fake press release style info to go along with it. It was NOT made by Cryptic/Paragon, just a fan.
If anyone still has this and could upload it, that would be awesome. I can't find it anywhere.
