Great delivery, great price, great book!
Format: Hardcover
Must have for any Batman/DC comics fan. I’m not much of an art snob, but the pictures in this book are stunning. The story is wonderful.

Solid Omnibus
Format: Hardcover
This omnibus collects some of the best stories for batman fans. The hard cover at first glance is bland and seems like an after thought but can easily be overlooked. Its a black cardboard material similar to the omnis that DC keeps dishing out non stop. Keep the dust jacket on after reading and it will look great on your shelf. The binding is similar to the new omnis coming out recently from DC and it stays flat when reading and isnt tight. Its a sewn binding and I havent had any issues. As far as the pages go their not too thin and not too thick. The colors really come out and the shades of black really look well done and you can tell they didnt just reprint. There was some thought that went into this. There are some really cool extras in the back which makes up for the overall price. In all this is a giant collection of some awesome stories and my review is a little all over but you want a reason why its 5 stars.

Looking for the perfect gift for a Batman fan? Get this!
Format: Hardcover
Before you buy this for a Batman fan, please make sure they already own it :) This collection is amazing, and it's perfect for a Batman fan that may appreciate a nice high-quality graphic novel featuring their favorite hero.
This story features some of the best storylines in the history of Batman, and personally, I LOVE the art style.
This is the PERFECT starter book for a fan of the Batman movies, shows, and games. Many fans who don't collect or read comics feel that way because following the single issue releases of ongoing comic series can be difficult and confusing.
This collection includes several complete stories that serve as an amazing starting point for any comic or Batman fan.
