First US pressing of Rolling Stones' Their Satanic Majesties Request has a lenticular plastic 3-D image of the band (which is hard to capture in a photo)--artsy fartsy in the mind of a 13-year old boy.
First UK pressing of Bob Marley's Catch a Fire has a cover designed like a Zippo lighter. It flips open like a Zippo, too! Fuck art. Let's light up, man.
