Lords of prog rock Pink Floyd are collaborating on a major new exhibition of memorabilia and props - including the famous inflatable pig which starred on the cover of their 1977 album, Animals.

The three surviving members of the band - Roger Waters, David Gilmour and Nick Mason - are marking their 50th anniversary with Their Mortal Remains, an exhibition which will bring together 300 artefacts from their recording and performance career.

Described as a "multi-sensory" experience, the exhibition will chart the band from their 1967 debut album The Piper At The Gates Of Dawn onwards but will also include some solo elements.

Their Mortal Remains will open at an old factory in Milan, Italy, covering 2,500 sq m in September this year and there are hopes it may visit other locations.

Among those working on the project are Aubrey Powell, from the Hipgnosis art team which masterminded the band's artwork, and the firm Stufish, which worked on their stage designs.

"There were elements that just had to be included," Powell said. "For example a 20m (66ft) wide sculpture of The Wall, 5m (16ft) high inflatables and of course a flying pig.

"We shall be aiming for state-of-the-art, visuals and sonic delivery, similar to the experience of attending a Pink Floyd concert - you never know what to expect next."

Tickets go on sale on Thursday, February 27 for the exhibition which will be staged at Milan's La Fabbrica Del Vapore from September 19.
