I was of the understanding that these 'comic books' (Graphic Novels)
were only downloadable from Exo-Force website (a silly marketing mistake in
my opinion). Fans would download them and perhaps print them out and bind
them (told you it was a silly marketing mistake). I am not trying to
imply that this is what has happened here. However, if they are homemade copies,
then I think this would obviously be breaking the Bricklink policy to have them
in the catalog.
