Favorite album art?

There are lots to choose from, but my favorite album art is the ocver from Derek & The Dominos Layla. I also like Smashing Pumpkins Melon Collie for its art work. What are your favorites?
Eagles-Hotel California

Black Sabbath-Black Sabbath

Most of the YES albums
Herb Alpert's Tijuana Brass - Whipped Crean & Other Delights
Jimi Hendrix's "Electric Ladyland" from the Germany release album. My favorite as a young man. :)
It's gotta be Big Brother and Janis's "Cheap Thrills" By R. Crumb
There were also a few New Riders of the Purple Sage that were simply beautiful. Or, how about the Dead's "Aoxomoxoa"? I know, I know, My sixties are showing.
check out anything from hypgnosis. they designed many of the classic lp covers from the classic era....
A few more that quickly come to mind:

Ogden Nut Gone Flake by Small Faces
First Led Zep album
Nevermind Nirvana
Kiko Los Lobos
Kiln House, Mystery To Me, and Tusk from Fleetwood Mac
London Calling The Clash
Living Stereo Marti Jones & Don Dixon
Happy Trails Quicksilver
More Songs About Buildings and Food Talking Heads
"Blues for Allah" Music by Grateful Dead art by Philip Garris
"Tales from Topographic Oceans" music by Yes art by Roger Dean
"Brain Salad Surgery" Music by ELP art by HR Giger
"Dark Side of the Moon" Music by Pink Floyd art by Hipgnosis
Strange Days
Late For The Sky - Jackson Browne
Harbor Lights - Bruce Hornsby
Abbey Road - The Beatles
"In the Court of the Crimson King", King Crimson
"Looking In", Savoy Brown
"One Good Turn", Mark Colby
and this just arrived in the mail today,"...Little Broken Hearts", Norah Jones, totally hot!
I always admired Roger Dean. However, my favorite was the inside of the "Eat A Peach" album.
"In the Court of the Crimson King", King Crimson
Abucktwoeighty you beat me to it
Be Bop Deluxe "Sunburst Finish"
Anything by the Rippingtons, Spyro Grya-Carnaval and Morning Dance, Journey-Revelation, Santana-Abraxas, Kansas- Song For America, Leftoverture and Kansas,
Joni Mitchell-Both Sides Now and Clouds, ELO-Flashback, Boston-Boston and Don't Look Back, Styx-The Grand Illusion.

There really are too-too many to list. That must be a cool job, designing album covers.

I wish AudiogoN would allow polls, we could vote on our top five or something. Maybe a bracket system like the March Madness, Jazz, Rock, Classical, Blues, New Age etc...???
Check out the books "Album Cover Album" for some really neat covers. I think there are 7 or 8 volumes. I have all of them. I know there are several other books, but these are the best. They are authored by Roger Dean and Storm Thorgerson.
Roxy Music - Avalon
Sgt. Pep.
All Things Must Pass
most of the Yes albums
Rush "Moving Pictures"
Floyd's Wish You Were Here only because the corporate greed (and banking prophecies) have come true.

Art imitating life imitating art.

But also anything by Storm Thorgesen's Hipgnosis.
I always liked Mahogony Rush" Strange Universe "
I'm with Alpass. I also love Laurie Anderson and Residents album arts.
Eat a Peach - I need a Google Chrome theme and was looking for this or maybe a Roger Dean or one of the Grateful Dead covers but no luck. Lots of video game themes and artsy stuff, and oh, I forgot Justin Bieber - goes to show the age group making this stuff. Maybe I should just stick with a newspaper and corded telephone instead of a computer :>)
Mgattone-excellent cover in deed.
My favorite list is long. But Ralph Steadman did some artwork on a couple Ambrosia albums I've always admired.
And of course the many listed above. I've often thought Brain Salad by Geiger would be awesome for helmet graphics.
Happy 4th to all, John
Mofimadness, thanks for the album cover album reminder. Forgot I had one, circa 1977. Lots of great stuff.
Blue Cheer, "Outsideinside"

and how about that plate of mexican food inside ZZtop's Tres Hombres?
The Santana debut. The more you examine it the more you find. This would have been an easy one to trip out to in the 70s. May explain why the vinyl is usually trashed when you find one.
Whipped Cream and Other Delights - Herb Albert and the Tijuana Brass.

In Search of the Lost Chord - Moody Blues

"Teensville" - Chet Atkins

Others already mentioned - "Crimson King" (maybe my favorite)and "Looking In"
