Just imagine Lars describing the philosophy behind this artwork:
"Well, um, it's like this magnet, you know, that, um, attracts metal things, but it's, like, it's in the shape of a coffin, so it's, like, death. But magnetic. Like."
They are probably broke so they didn't hire someone to make their album cover , i believe that this design is what's left in their heads A BIG MAGNETIC ANUS
