The list author says: "The Walking Dead is a fantastic black and white zombie book from Image Comics. The books have been in available in TPB, oversized hardcover, and omnibus form. There is also a softcover compendium containing the first 48 coming out later this year."
"This book contains issues 1-48. It will be a paperback. This book is not yet released. However, it's hard for me to recommend this book for the simple purpose of it being too big for its binding. Chances of the binding being ruined are pretty likely."
