Dark Knight DVDs

Joblo recieved these images from an Czech site.

A scooper named “Dave” sent in some images that we’ve been able to confirm
as legit. They would confirm a 2-disc DVD, a Blu-ray, a steelbook 2-disc DVD
special edition, a Batpod collector’s DVD and a Batman mask collector’s DVD
(basically the 2-disc DVD
shrink-wrapped with a Batman mask).

Just like The Hulk cover, the two disc isn’t good, they should’ve picked better images. I recommend the steelbook verison. Why is the mask collection necessary?
