On Saturday, Prince Andrew shared an incredible throwback photo taken from his childhood to mark the 50th anniversary of the historic moon landing. The Duke of York posted a black-and-white picture of himself as a child with his siblings Prince Edward and Princess Anne, meeting Neil Armstrong at Buckingham Palace. The photo went down a treat with many of Andrew's followers, including his ex-wife Sarah Ferguson, who liked the picture. In the caption, the father-of-two wrote: "To mark #MoonLanding50, here's a photo of Prince Edward, Prince Andrew & Princess Anne, meeting Neil Armstrong at Buckingham Palace. The Astronauts of the Apollo 11 Space Mission visited London as part of a 22-nation world tour in October 1969.
