Proving there's a firm fan of the show hiding within The Firm, the Queen's official Twitter account @RoyalFamily shared the history behind the key scene.
Taking to the social media platform, a member of the regal social media team shared the referenced shots of a young Queen Elizabeth II which were imprinted on postage stamps from 1953 to 1971.
"These photographs taken by Dorothy Wilding, of Her Majesty in 1952, were used as the basis of The Queen’s image on postage stamps from 1953 until 1971," the caption states. "In two sittings, photographer Wilding took 59 images of the Queen."
A follow-up tweet also depicts the most famous profile of Her Majesty which has been featured on UK stamps since 1967.
"Arnold Machin's effigy of The Queen, which has featured on UK stamps since 1967, is widely considered to be one of the most reproduced and iconic images in the world," the tweet reads. "It has been reprinted an estimated 220 billion times, in more than 130 different colours."
The opening scene of The Crown season three features a brief cameo from predecessor Claire Foy who took to the throne in seasons one and two.
Earlier this week, it was revealed that the award-winning actress will return for flashback scenes in the next installment after photographs of her back on set went viral.
Until then, season three of The Crown is currently available to watch on Netflix.
