This oversized comic book by French artist David B., is a spinoff of his wellknown graphic novel Epileptic.
The book explores the relationship of dreams to personal mythology and history, weaving into the narrative historical battles, fantastical figures, and his brother's struggle with epilepsy.
Overall, the book is wonderfully designed, with large front and back flaps (one of which is pictured above).
The outer cover can be removed to reveal this one underneath.
I've just noticed that the second issue of Babel is available, so I'll have to go check that out.
