From the publisher:

After many years of talking about Moby-Dick (the book and the film), Victorian ghost stories, comics, folklore and history in general, Mike Mignola, Hellboy, and Gary Gianni embarked on a graphic-novel adventure titled Into the Silent Sea. Mike Mignola's Hellboy: Into the Silent Sea Studio Edition is a glorious, oversized deluxe treatment showcasing Gianni's original artwork in an exquisite hardcover book. The 144-page collection includes revealing commentary regarding how two legendary comic-book creators seamlessly developed the Hellboy sea saga from the core of an idea into a finished work of art. The combined talents of Mignola and Gianni are on display as the reader follows along the path of the creative process: The script, preliminary roughs, reference photos, completed pencil drawings and finished inks are all shared and discussed. The pencil drawings, many of which have never been seen before by the public, provide insight not only for the student but also for any fan who enjoys lavishly reproduced comic art.
