What's up with comic book boobs?
No, not just the absurdly big ones, although they're part of it.
Are there any comic book artists out there who draw more than one kind of boobs?
There are tons of artists who draw the absurdly big ones, as I'm sure you've noted. Too many of them look remarkably like they were modeled on fake boobs, at that, but that's not the point here either.
There are a few who draw the cutesy little poky boobs.
There are the fewest still, it seems, that draw them in the average range.
But having lived a long life in which I've spent more of that time than I ought to have observing women's breasts, I have to say that if there's one thing that's clearly true. In the real world, breasts vary greatly and regularly in size and shape. It's part of what keeps them interesting to keep observing, I think...
But is there even one comic book artist that draws them with variety?
Seriously. I'd like to hear an answer of just one, and it has to be a real variety, not just someone who happens to draw Power Girl with larger breasts than Wonder Woman.
