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.
Rubber Soul/Revolver/Sgt Pepper; the ones that started it all, including Storm Thorgerson and his Hignosis group.
Whipped Cream and Other Delights
In the Land of Grey and Pink (Caravan)
In The Court of the Crimson King
Terrapin Station (Grateful Dead)
Something for Everybody (Devo)
Cream Wheels of Fire
Rolling Stones Their Satanic Majesties Request
Beatles Sgt. Pepper's Lonely Hearts Club Band
Rolling Stones Some Girls
Jimi Hendrix Axis Bold as Love
Brain Salad Surgery (ELP)
Almost any of the YES album covers
AJA & The Royal Scam (Steely Dan)
Hotel California (The Eagles)

I have all of the "Album Cover Album" books and there are a lot of excellent covers. If you ever get a chance to look through these volumes, it's really pretty cool.
+1 for Whipped Cream and Other Delights. And how about

Blue Cheer--InsideOutside

Steely Dan--Countdown to Ecstasy
All of Iron Maden covers and posters all all all.
I keep records in collection simply because of covers, but not big fan of their music.
American Beauty, Exile on Main Street, All Things Must Pass, Axis:Bold as Love, Who's Next, Zep III and the best of the best Sgt.Pep.

The Band: The Band (the brown album). The pics on the inside of the gatefold cover are great too. The best album cover, of the all-time best album, by the best rock n' roll band of them all. Three for three! Actually, it's a tie between this album and their first, Music From Big Pink. Just ask the best musician you know, he'll tell ya (he'll agree with Eric Clapton, George Harrison, Bob Dylan, and thousands of others).
I like generic covers for dance singles. No worries about wear and anytime you can replace'em by nu.
The Thievery Corporation / It Takes a Thief

Inside the cd fold out...Such COOL guys & working environment!!! Love the MUSIC as well.
No particular order: Be Bop Deluxe - Sunburst Finish, Zappa - One Size Fits All, Tangerine Dream - Atmasphere, Gentle Giant - In a Glass House, Walter Carlos - Switched On Bach I & II, Clockwork Orange soundtrack.

I second Maiden's CD artwork, but unlike the above post, I've been into Maiden for three plus decades.
Bill Evans and Jim Hall, "Undercurrent" (artist's photo of woman swimming, taken from below - I mention this because I've seen reissues which are different).
1972 First album by a group called "Mom's Apple Pie". Google it and you'll see why!
Abraxas, Tales from Topographic Oceans, Barboletta, Disraeli Gears, Physical Graffiti, Eat a Peach, Question of Balance, Santana 3, But Seriously Folks
The Beatles Butcher Cover. Mammas and Pappas with Mamma sitting on a toilet. Lynyrd Skynyrd Flame cover. All banned of course.
Led Zeppelin's creepy Houses of the Holy!
Creepy Black Sabbath's self titled!

But the best has to be The Beatles' Sgt. Pepper's Lonely Hearts Club Band.
I like Mark Ryden's work in general very much, in particular the cover art for Bigger Better Faster More by Three Non Blondes. He also did MJ's Dangerous and RHCP's One Hot Minute album covers. More please, Mr. Ryden.
Mothers of Invention had some good ones, not the least of which were We're Only in it for the Money and Lumpy Gravy, the Sgt. Peppers take off and the band in drag, respectively.
Most of the time in my memory Delicate Sound of Thunder, but I can't really tell if it's my favorite album cover of all times. Sid's covers are great as well.
Captain Beyond/ Sufficiently Breathless and Hawkwind/ Hall of the Mountain Grill. Favorite music also...
