Here is the actual cover for the City of Blinding Lights single. (taken from u2.com) I like it a lot. I was a little skeptical after seeing the promo cover but this makes me happy.
Sometimes the artwork leaves a lot to be desired, but this is a very cool looking cover. More in the vein of Achtung Baby/Zooropa/Pop - there were some really interesting covers then.
All I need now are for them to start releasing vinyl properly again. Then I can have really cool, really big covers!
