Every issue of 2000AD comes with two perfectly good logos, which beggars the question - why not just pick one or the other, Tharg?
Yeah, always puzzled me, too.
I'm guessing it's because it makes it easier to spot on newsagents' shelves. If most of the right side of the cover is obscured by some other magazine, you can still see the smaller logo, if most of the left side is covered, you can still see the "AD" of the larger logo.
