We’ve seen plenty of baby pics of the Royal Family’s youngest members (see Prince George holding his baby sis and Princess Charlotte at her christening), but there’s one Royal whose earlier days we’re seldom privy to: Queen Elizabeth II.

The monarch turned 91 years old today (though you’d never guess it from the snaps of her taken on Easter Sunday, looking as shrewd as ever), and to celebrate, the Royal Family shared a throwback shot of the Queen Mother like you’ve never seen her on its Instagram page.

“Happy birthday Her Majesty!” reads the caption. “As the Queen turns 91 years old today, we wanted to share a rare photograph of Princess Elizabeth (as she was known then) as a young child.”

Even then, Queen Elizabeth seemed destined for royal greatness, raising her little hand to greet what were surely her adoring fans. “The two-year-old princess is pictured waving from her carriage as it drives through London in 1928.” Wow!

89 years later (and one year after her first Tweet), the Irish Guards Band are blowing their horns to the tune of “Happy Birthday” to wish the now-ruler (the oldest living monarch there is) a great one.

Perhaps, should you snag the open gig as her “curtain maker and soft furniture upholsterer” that’s up for grabs, you can wish her a happy belated in person too?

Happy birthday, Queen Elizabeth II!

Are you surprised to see the Queen as a babe? Tell us over @BritandCo.
