Speaking of MAD Magazine: One of the more interesting new artists drawing for that publication is Hermann Mejia. I like his artwork a lot but have been especially impressed by his statuary. He's done some amazing sculptures of famous people.
Hermann has just set up his own website and it has examples of his painting and drawing on it. But I call your special attention to his gallery of sculptures. Take a look at his renderings of George W. Bush, Donald Rumsfeld, Dick Cheney, Condoleezza Rice, Saddam Hussein and DC publisher Paul Levitz. I don't think Paul will feel insulted by the likeness of himself but he might by the grouping.
