Best Album Covers Of All Time

What do you think was the best album cover ever created? Pink Floyd's The Dark Side of the Moon?, The Beatles' Sgt. Pepper's Lonely Hearts Club Band? Whatta ya got?

I absolutely adore my record collection for two reasons, 1.) I love the sound of vinyl, and 2.) I love the record jacket. Album covers had to look awesome during the days of vinyl, they were huge and in-your-face, practically selling the record inside in itself. Usually though, a classic album cover contains a classic album.

I've got a lot of classic album covers/albums. I've got The Rolling Stones' Sticky Fingers (with an actual zipper on the jeans, gotta love that), Joe Jackson's Look Sharp! (those are some slick white shoes), The Cars' Candy-O (an absolute classic), and Santana's Amigos (just one of his many amazing, trippy covers). Those are just a few notables. Who, in your opinion, had the best album cover of all time?
