Found these over at Newsarama earlier a giant sheet with all of the new logos on it! Obviously you can click on it for a much, much larger image.
Some of them like the Superman family of titles, and Green Lantern family have seen very little change. Several of the Bat books are seeing changes, though not Dark Knight or Batman and Robin. Grifter, Static Shock, and Resurrection Man are among my personal favorites.
Blackhawks and Hawkman though? Not so much.
What do you guys think?
