Today is the Day

So this is a link to a series of picture that I thought was interesting
http://istheday.blogspot.com/ . It made me wonder what must be in a comic for it to be a comic, or graphic novel. These are static images using abstract representations to tell a story from panel to panel. One of my hang-ups on why a graphic novel may not be literature—although I think it may be—is the use of painting and drawing. Nobody would consider a statue with a plaque to be literature.
