On Sunday June 2 2019, Queen Elizabeth II (93) celebrated the 66th anniversary of her coronation. On this occasion, the Royal Collection Trust posted a throwback photo on Instagram showing the then 5-year-old Prince Charles (71), his grandmother Elizabeth Bowes-Lyon (†101) and his aunt Princess Margaret (†71) at the ceremony.

The caption read: "On this day in 1953 The Queen’s coronation took place. This photograph shows a young Prince Charles standing between his grandmother (Queen Elizabeth The Queen Mother) and aunt (Princess Margaret)."

The little Prince Charles, however, looks anything but cheerful in the picture. He just looks as if he's somewhere else. Which is understandable, since the ceremony took about three hours.

On Instagram the comments then started piling up under the funny throwback photo. One user jokes, Prince Charles might still be waiting for the time of his own coronation. Another user suspects how Charles must have felt at that moment: "Prince Charles: 'This may take a while'".

Especially amusing: The picture looks almost exactly like a photo taken in June 2017 of Prince Charles' grandson Prince George (5). At the annual 'Trooping the Colour' parade for the occasion of the Queen's birthday, he also seemed a little bored.

The 'Trooping the Colour' parade took place again this year in honour of the Queen's 93rd birthday. The parade has marked the official birthday of the British sovereign since it first took place in 1748 - it is held every year on the second Saturday in June.
