If Super Hero Thanksgiving isn't enough to prove Kerry Callen's awesomeness, his quartet of animated covers to classic comics ought to do the trick. Comics Alliance has the whole set, including The Amazing Spider-Man #33, Batman: The Dark Knight Returns #1, Iron Man #128, and this one, Justice League of America #6.

[Updated: See the comments below for the explanation, but my not linking directly to Callen's blog where he originally posted these was an oversight on my part. I apologize.]
