'The covers of comic books/graphic novels/sequential narratives, call them what you will, have a fundamentally different relationship to the contents of their books than the covers of ‘ordinary’, text-only works. For the latter, the cover image is usually produced by a designer whom the author does not know and may never meet. In the case of comics, however, the cover image is made by the same hand that creates the images that proliferate within the book. The cover of a text-only book is communicating a sense of what the book is like through the totally different language of images. For the browser, that’s like trying to decide whether to attend a concert on the strength of a billposter. With a comic book, the sort of thing you see on the cover is the sort of thing you get inside. A comic book begins before you even open it. Basically, you can judge a comic book by its cover.'
