Well, if it isn't, it very well could be. Online today, illustrator Paul O. Zelinsky answers 7-Imp's Seven Questions Over Breakfast and chats about his work at Just One More Book. Not to be missed, especially if you're interested (as I am) in fairy tale retellings..
For the record, I consider Zelinsky to be past master of the art of fairy tales. His Rapunzel (Dutton, 1997) is an exemplary book: beautifully retold and illustrated in oils, following the traditions of Italian Renaissance painting. The source notes (I love source notes) are both scholarly and insightful. Rapunzel won the Caldecott Medal in 1998.
Zelinsky says he's not good at choosing favorites. Neither am I, ordinarily; but I can say that Rapunzel is mine.
