Each volume reprints out-of-print back issues, plus a significant amount of previously unpublished material. All the Collected Jack Kirby Collectors are now out-of-print themselves.

From the publisher:

This trade paperback reprints the sold-out issues #10-12 of the bi-monthly magazine for Kirby fans and includes a new special section detailing a fan's visit to the Kirbys' remarkable home. This private tour is profusely illustrated with photos, and more than 30 pieces of Kirby art never before published in TJKC, including Jack's uninked pencils from The Prisoner, New Gods, Captain America, Thor, Hunger Dogs, Jimmy Olsen, SHIELD, Machine Man, The Eternals, and more! Learn more about the King's career through interviews with Jack and Roz Kirby, John Byrne, Steve Gerber, Mark Evanier, Roger Stern, Marv Wolfman, and page after page of rare Kirby art, much in its original pencil form. Join us in celebrating the life and career of comics' most prodigious imagination: Jack Kirby!
