David Bowie's landmark album Ziggy Stardust has been celebrated with a blue plaque.
Former Spandau Ballet star Gary Kemp - a near lifelong fan of the pioneering musician - unveiled the plaque at the spot where the cover of the 1972 release was shot.
The location, in Heddon Street, just off Regent Street, in London is now a pedestrianised area brimming with bars and restaurants.
The album - fully titled The Rise And Fall Of Ziggy Stardust And The Spiders From Mars - helped to establish Bowie as one of the world's best known rock stars.
It featured just one top 10 hit, Starman, but established him as a visionary and showcased his changes of image.
Kemp - who became hooked by music after seeing Bowie in his Ziggy guise on Top Of The Pops - described him as a "Messianic rock star".
The cover was shot in January 1972, five months before the release, with Bowie resting his foot on a step outside 23 Heddon Street, which photographer Brian Ward used as a makeshift studio.
Bowie wore a green jumpsuit, later featured in a performance on BBC music show The Old Grey Whistle Test, but it was hand coloured to appear blue on the sleeve.
The singer has said of the shoot: "It was cold and it rained and I felt like an actor."
