I've never read "The Picture of Dorian Grey" myself, but I'm at least vaguely familiar with the Oscar Wilde story. It's about a guy who doesn't age, rather he has a portrait that ages in his stead. As far as I know, in the book he's not immortal like he is in the movie.

As for the comic, I believe there is a background panel reference to Dorian Grey in one of the issues, but that's it. He's not in the comic, nor is Tom Sawyer.
