The cover shows 700 hospital beds placed on Saunton Sands, Devon. This effect was not achieved with trick photography; a team actually hauled the wrought iron beds over three hours from London to Devon and arranged them as seen on the finished design. When the team realised that the shoot would take more than one day, a single bed was left on the beach to see if the sea would have any effect on it over night. When they returned the following morning, the bed was nowhere to be found. Long-time Pink Floyd collaborator Storm Thorgerson produced the artwork.
In the sky in the backdrop there is a person flying a Hang Glider, probably a reference to Learning to Fly.
Storm Thorgerson comments the cover shot on his website: 700, yes 700, wrought iron hospital beds separately made up and positioned on the beach. Madness to do it at all, but we had in fact to do it twice cos it rained suddenly the first time, dank grey dizzle, and we couldn't see the distant half of the beds.
