The note reads: "The Duke and Duchess of Cambridge appreciated your kind thought in writing to Prince Louis as you did on the occasion of his second birthday. This was greatly appreciated by Their Royal Highnesses who send you their best wishes."

The photo was taken by the duchess at Anmer Hall, the Cambridges' family home in Norfolk. Kate Middleton is known for capturing photos of her family and often shares pictures that she's taken of Prince George, Princess Charlotte, and Prince Louis through the years.

Some royal fans pointed out that in the previously unseen photo of Prince Louis, the young prince looks like his older brother, Prince George, who turned 7 in July.

Among Prince Louis' birthday photos released in April were candid and "Instagram vs. Reality" shots that showed him having fun with rainbow paint.

Representatives for the Duke and Duchess of Cambridge did not immediately respond to Insider's request for comment.
