There has been quite a bit of literature published over the last 20 years on the intersection of comics and so-called fine-art. Journals like the Journal of Popular Culture, Print, and the International Journal of Comic Art (
http://www.ijoca.com/) have dedicated space to this issue. One of my favorite articles from the Comics Journal
http://www.english.ufl.edu/comics/scholars/TCJ_Index.html discussed the matter under the rubric, "Who is the better artist, Jack K or Roy L?" (quoting from memory). Kirby (and the EC artists) were judged inferior in that article, if I remember. I think that many caroonists and comic scholars (even those with fine art or literary pretensions/reputations) today would beg to differ with that verdict, which I think was intended as something of a provacation to the insular comic fan world, but still valid in some sense.
Here is a list of some other articles, from the Comic Research Bibliography:
