Jordan Crane's amazing cover for Michael Chabon's Maps and Legends
Additionally, the subject for the book is fascinating. It contains a series of essays on genre fiction. Very fun, as he covers some favorites, like Philip Pulman's His Dark Materials, Cormac McCarthy's The Road, and Will Eisner.
Can't say that I have had such fun reading literary criticism for quite some time! And the cover rocks, take a look at the www.boing.boing.net photos.
