All of these fantastic album covers are from Sleevage, a great blog devoted to album cover design. If you like what you see here, be sure to check out the site, as there's lots more to see — plus great commentary on the history of these designs, too. I own a couple of these, actually — New Order and Massive Attack. Via ffffound.
