'Atom Heart Mother' - A signed limited edition silkscreen of a Pink Floyd album cover by Storm Thorgerson.

The original album cover shows a cow standing in a field with no text nor any other clue as to what might be on the record. This concept was the group's reaction to the psychadelic imagery associated with Pink Floyd at the time of the album's release; the band wanted to explore all sorts of music without being limited to a particular image or style of performance. They thus requested that their new album had "something plain" on the cover, which ended up being the image of the cow. Thorgerson, inspired by Andy Warhol's famous "cow-wallpaper," has said that he simply drove out into a rural area and photographed the first cow he saw.

The album cover appears in Stanley Kubrick's film A Clockwork Orange. It is viewable on a shelf in the music shop scene.
