When I was a kid, my Dad had an old stack of Classics Illustrated, which are/were classics rewritten in comic book/graphic novel form. I guess they're out of print, which is too bad, because some of the books are ones I would never ever have waded through in their original form, but the stories were a lot of fun and some of the illustrations were very vivid and stick in my mind today (e.g., the Fall of the House of Usher, the Pit and the Pendulum, Pitcairn's Island). Here's the Wikipedia entry on them. I did get a used one on Amazon for about $12 awhile ago, so pretty pricey, but maybe somebody will start printing them again??
