I have submitted to core if that helps.
There is an Into the Silent Sea Hardcover in Core already, but this is a different publisher, Different Edition entirely, and this one is more of a process book than a reprint. It is signed by both Mignola and Gianni and includes two additional prints signed by Gianni.
