Being a comic book creator folks have to promote their products virtually every waking moment - between these three creators - who is the biggest, knock down, drag out promoter?
BUT - I have one rule - the playing field must be level, while Stan Lee has been promoting the comic industry for over a half century - I would rather we focus on their methodology to pimp their own work.
Thus if each of those three were the same age, had the same access to the same media outlets, who would pimp out their product the best?
..and why?
