A never before heard demo track by David Bowie recorded years before his first big hit is being sold at auction.
The song 'I Do Believe I Love You' was recorded in 1966 and showcases a rare style of mainstream 60s pop music for the star.
The unique acetate recording is expected to fetch up to £5,000 and has only previously been heard by a few people.
Bowie shot into the public consciousness with 'Space Oddity' three years later and went on to become an icon. He passed away in 2016.
The song was recorded when Bowie was signed to Orbit Music Publishing, whose owner also worked with The Who and The Kinks.
The track seemed destined to be forgotten until it was discovered by a private seller among a back catalogue collection.
It is now being sold by Wessex Auction Rooms in Chippenham, Wilts, on July 24 - and has been priced at between £3,000 and £5,000.
Auctioneer Martin Hughes said: "As one of only a few people in the world who has heard the recording, I am still amazed that this musical treasure has been uncovered after all of these years.
"David Bowie is one of the most iconic artists of all time and I am sure that this item is going to create a buzz around the globe amongst fans as well as collectors of pop culture."
The lot is now available to view online.
