This 200 page, full size hardcover volume is primarily what the title indicates. From thumbnail breakdowns to idea sketches and on through to profoundly beautiful fully realized illustrations of related to the themes and characters of the Edena Cycle, this book is filled with amazing art. But there's more: there are also comics that were not included in The World of Edena. Some are variations on sequences that you've seen before (presuming that you've already read the aforementioned World of Edna [if not, what are you waiting for?]), others are new, and only tangentially related – but from the same period – such as two pieces related to visiting Naples. Suffice it to say, if you're a Moebius fan, this is essential; if you're a fan of imaginative comics and illustration, this is recommended. Jean Giraud – aka Moebius – was in a class by himself.
