Your favorite album cover...

Album cover art ain't what it used to be.
I always admired the R. Crumb Big Brother cover.
Sticky Fingers is worth framing.
Hated Beggars Banquet and the White Album covers.
Neon Parks was fun, the Last Record Album and Weasels Ripped my Flesh come to mind.
London Calling is my favorite, a take off of an old Elvis album cover that captured the spirited intensity the band was producing at the time.
Have to modify the question to scariest album cover of all time. "In the Court Of The Crimson King." Scared the crap out of me in 1970. Still does.
The Beatles Sgt. Peppers
The Beatles Revolver 
The Allman Brothers Eat A Peach
Pink Floyd Animals 
Little Feat Waiting For Columbus 
Yes Fragile
Pure Prairie League Two Lane Highway
Pure Prairie League first Album cowboy with phonograph

Led Zep III- with the spinner thing.

and if you open the album to the middle (so not really a cover) - Led Zep IV.
