There's a nice little article over at io9 about the history of Hellboy. Link

The recipient of the Caldecott Medal in 2008 is Brian Selznick for his book, The Invention of Hugo Cabret. The Invention of Hugo Cabret follows a young boy, Hugo, on the streets of Paris in the early 1900's as his curiosity and his past catch up with him following his fathers death.

In a uniquely stylized book, Brian Selznick has separated words and pictures as the story is told. The experience of the book is much like that of a silent film making the method used to tell the story just as magical as the story itself.
