A major exhibition devoted to rock band Pink Floyd which had been expected to draw fans from around to Europe to Milan has been postponed.
Artefacts from throughout the band's career including a giant inflatable pig and a sculpture of The Wall which was built on stage during some of the group's live shows were to feature in the display called Their Mortal Remains, being partly built in the UK.
It had been due to open on September 19 but sales have now been suspended when organisers realised they would not make the start date. A revised opening date has yet to be announced.
Devotees were expected to fly over to visit the exhibition from the UK and elsewhere, to see the attraction at an old factory in the Italian city, La Fabbrica Del Vapore, covering 27,000 sq ft (2,500 sq m).
A statement on behalf of organisers said: " Evolve Devolve, the Italian promoters of The Pink Floyd Exhibition, have announced today that the exhibition, due to start on 19 September 2014 in Milan, has had to be postponed due to production delays. Building the complex exhibition to the required specification has made it impossible to make the opening date."
Ticket-holders can exchange them for an alternative date once these are finalised or they can seek a refund.
The three surviving musicians - Roger Waters, David Gilmour and Nick Mason - have been involved in planning the "multi-sensory" exhibition which is to bring together around 300 items from the band's decades of recordings and performance.
An album of unreleased material, based on 1994 sessions - after Waters left the band but featuring keyboard player Rick Wright who did in 2008 - is to be released in October, called The Endless River.
Next year will mark the 50th anniversary of the group's formation.
