The 50th anniversary of one of Led Zeppelin's most iconic albums was celebrated across the world this week.
Monday, November 15, marked 50 years since the band's fourth untitled album was released.
To celebrate, walls, billboards and even a blimp were adorned with the album's artwork in cities across the world including New York and London.

The album is the band's biggest commercial success, having sold £37million copies worldwide, and features tracks such as Black Dog, Rock and Roll and When the Levee Breaks.

It was also named Classic Rock's greatest ever rock album whilst Mojo, Rolling Stone and NME all named it as one of the top 500 albums of all time.

Lead singer, Worcestershire-based Robert Plant, had a hand in writing every track on the legendary album.
