Executives at Air Artists, the firm behind the floating porky, are selling off the blow-up pig as part of a rock memorabilia sale, which will also feature items created for the Rolling Stones, Iron Maiden and AC DC.

Inflatables artist Rob Harries, who designed many of the larger-than-life props, tells the BBC, "I'm sad to see them go but they very rarely see the light of day... The clear-out has been quite cathartic and brought back a lot of memories."

The Pink Floyd pig, which was photographed flying above the London skyline, comes with quite the backstory - it grounded flights from Heathrow Airport after breaking free and ended up coming down in a field on the outskirts of the capital.

The inflatable flew again in 2011 as part of a stunt planned to publicise a run the band's remastered albums.

The pig will be sold at an upcoming Durrants auction in the U.K.
