In the mid 1970s, a bootleg containing rare singles and B-sides entitled The Dark Side of the Moo appeared, with a similar cover. Looking back on the artwork, Thorgerson remembered 'I think the cow represents, in terms of the Pink Floyd, part of their humor, which I think is often underestimated or just unwritten about.' The liner notes in later CD editions give a recipe for Traditional Bedouin Wedding Feast on a card labelled 'Breakfast Tips'. Also, a pink balloon shaped like a cow udder accompanied the album as part of Capitol's marketing strategy campaign to 'break' the band in the US. More cows appear on the back cover, again with no text or titles, and on the inside gatefold. The cow's owner identified her name as 'Lulubelle III'. Storm Thorgerson, inspired by Andy Warhol's famous 'cow-wallpaper,' has said that he simply drove out into a rural area near Potters Bar and photographed the first cow he saw. They thus requested that their new album had 'something plain' on the cover, which ended up being the image of a cow. This concept was the group's reaction to the psychedelic space rock 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. Some later editions have the title and artist name added to the cover.

The original album cover, designed by art collective Hipgnosis, shows a cow standing in a pasture with no text nor any other clue as to what might be on the record.
