Jack Davis is more than just one of the ten greatest cartoonists of all time (yeah, I said it)... he's a freakin' national treasure. His work in comics and illustration spans over five decades, numerous genres, and practically every major media outlet you can think of. While there have been a handful of books dedicated to his work, the definitive monograph has yet to be compiled.
Below is a Pops Gallery of some of Davis' best album covers, in as hi-res as I could find on the webby web. Sheer, unadulterated, manic genius.
