"In 1960, to celebrate [the Queen Mother’s] 60th Birthday, this photo was taken at Clarence House, and features a 6-month-old Prince Andrew sitting on her knee, Prince Charles, Princess Anne and a Corgi," the caption reads. "Until the accession of Prince Albert, The Duke of York as King George VI in 1936, Queen Elizabeth was The Duchess of York."
But it wasn't the caption that got people talking instead it was Prince Charles, who commenters were quick to point out looked the spitting image of a young Prince Harry.
"Wow. I see Prince Harry in Charles…amazing", commented one user, while another posted: "That is Prince Harry’s twin. This could be Prince Harry, he looks just like his dad."
This isn't the first time a royal photograph has gone viral for showing just how alike Harry and Charles are.
