Would you consider comic books art? I'm sure can agree that there are some out there that can definitely be considered art but what about more mainstream ones like X-Men or Superman? I ask this after reading X-23 One Shot which combined traditional comic book art with some more meta art. Here's are two examples of the more untraditional art the comic book featured when dealing with one of the character's mind.
Here's my two cent, I think that comic books are very much art. I think some have more artistic value than others but in the end they are both are and literature (even if just fast food literature).
