The 92-year-old Queen as Instagram influencer? We live in strange times, and they keep getting stranger. Queen Elizabeth has published her first post on Instagram, 43 years after she sent her first email.

The Queen issued her post—an epic throwback, natch—from London’s Science Museum. The post was a snapshot of a letter sent by 19th-century mathematician and computer pioneer Charles Babbage to Queen Victoria's husband, Prince Albert.

"Today, as I visit the Science Museum I was interested to discover a letter from the Royal Archives, written in 1843 to my great-great-grandfather Prince Albert," she wrote in the post on the official @TheRoyalFamily account, using a touch screen iPad at the museum to send the message.

She continued: "Today, I had the pleasure of learning about children's computer coding initiatives and it seems fitting to me that I publish this Instagram post, at the Science Museum which has long championed technology, innovation and inspired the next generation of inventors/"

Adorably, she signed the post Elizabeth R.

The royal account has 4.6 million followers. Users immediately welcomed the Queen to Instagram, as did the museum. Some users were cheeky, writing "hi liz!" while others were more restrained.

"We are honoured that while opening The Smith Centre at the Science Museum Your Majesty shared a post on Instagram for the first time," the Science Museum wrote in a comment on the image.

"We're thrilled that the image is of correspondence from the Royal Archive between Charles Babbage and Your Majesty's great-great-grandfather Prince Albert about the Difference Engine No.1 on display in our Making the Modern World gallery."
