Spiegelman has also done a string of excellent covers for The New Yorker magazine in recent years. One of them, following a well-publicized incident of NYPD brutality (I don't recall which incident) depicted a smiling NYPD officer firing his revolver at civilians in a sort of Coney Island shooting arcade; an Easter cover depicted the Easter Bunny crucified by the Internal Revenue Service.
Spiegelman doesn't get by on wit and "relevance" alone; he has serious talent and formidable technique. Technique?! Isn't that out of fashion? Not entirely.
On the subject of people who've bothered to learn their craft, The New Yorker has also taken to running art by Los Brothers Hernandez of Love and Rockets fame: From Forced Exposure to the Algonquin, in three easy steps. Go figure. They do good work, don't they?
