what's your favorite album cover?

Great Thread! Santana Lotus has got to take the cake IMHO.
King Crimson "Lizard" "Wake of Posideon"
Also Moody Blues "Seventh Sojourn"
How about all of the very artistic graphic designs of the ECM jazz label during the 70's? very avante garde modernism.
Joe Jackson trying to look like Sonny Rollins on "Body and Soul"
The solo recordings of Anthony Phillips "private parts and pieces I,II,III" if not for the music, certainly for the covers.

Abraxas - Santana
Bitches Brew - Miles Davis
Their Satanic Majesties Request - The Rolling Stones
Sgt. Peppers - The Beatles
Aqualung - Jethro Tull
and
John and Yoko's first album. (gotta be a collector's item)

Frank Zappa
Weasels Ripped My Flesh

Original "Velvet Underground" with peelable banana.

Ohio Players' Honey was always one of my favorites growing up.
