Prince Charles included a rare photo in the thank you cards he released one month after his 70th birthday.

The heir to the throne celebrated his special day on Nov. 14 and received tons of greetings from royal fans. Prince Charles managed to reply back to those who sent him their well-wishes.

Instagram account Crown Replies uploaded a copy of Prince Charles’ thank you card online. In the front of the card is a photo of the Prince of Wales sitting on a throne-like chair wearing an all-black ensemble.

“The Prince of Wales was very touched you took the trouble to write as you did on the occasion of his 70th birthday. His Royal Highness greatly appreciated your thoughtfulness and sends you his warmest thanks and best wishes," the text in the letter reads.

Kensington Palace also released some official photos of Prince Charles with his family to mark his recent milestone. In one of the pictures, he is sitting on a bench beside his wife, Camilla Parker Bowles. His sons, Prince William and Prince Harry, are standing behind him. His daughters-in-law, Kate Middleton and Meghan Markle are also in the photo together with Prince William’s children.

In related news, Prince Charles made headlines this week after it was revealed that he was hit by garbage and bottles during a near-death experience in London in 2010.

The documentary “Serving the Royals: Inside the Firm” revealed that Prince Charles knew that there was a protest going on at that time, but it did not stop him from driving to the theater using his favorite route. Royal editor Andrew Pierce said that the future king’s vehicle was surrounded by protesters.

“It could have been a very, very dangerous moment,” he said.

Other than the car being hit by bottles, paint cans and garbage bins, a stick was also shoved through an open window and into Camilla’s ribs.

But this is not the first time that Prince Charles risked his life while out in public. On Australia Day years ago, he was almost assassinated by a former anthropology student while he was giving a speech.
