This is the Convention Exclusive Hardcover in a larger format (magazine size instead of comic book size) and sporting a variant cover.
From the publisher:
Artist Ashley Wood's work on Doomed garnered him fan praise and an Eisner Award nomination; now, collected in one single volume are his four frightful tales of terror, originally written by Richard Matheson, Robert Bloch, and David J. Schow, and adapted by Ted Adams and fellow Eisner nominee Chris Ryall.
Also contained within are Ms. Doomed pin-ups and covers, and the entire thing is wrapped in an all-new wraparound cover from Ash, too.
