Hot Rod, valid point. But I think he's going for as generic a cover as possible. A lot of his stuff contains nonsequitur information because he's maintaining ambiguity and allowing for them to be used for any set, any DVD, etc. The specific point of these covers though, is so it looks like you're carrying around a Star Wars lunch box, so that's why I think he left them alone.
It's also good with these creative esoteric sources to keep them pretty much blank so they can be altered or used by somebody else. Like Darth Solo's manga sets, completely blank, but allows for them to be made available for a number of uses.
Anyway...
