Gert's Royal Replies shared a note they received from the Duke and Duchess of Cambridge in response to a condolences message sent following Prince Philip's death in April.

The reply, sent in an envelope adorned with royal mail stamp and the Kensington Palace logo, was a folded card featuring Prince William and Kate's individual monograms on the outside Inside shows a photo of Prince Philip in military dress from 2012 when he attended the Queen's Diamond Jubilee Armed Forces Parade and Muster at Windsor Castle. There's also a typed note, with both pages outlined with a black border that represents mourning.

"The Duke and Duchess of Cambridge thank you for your kind words following the death of The Duke of Edinburgh," the note reads. "Their Royal Highnesses have been incredibly moved by the many thoughtful messages they have received in recent weeks. They will all miss their much loved grandfather and great-grandfather, but your message has provided great comfort at this difficult time."

Following Prince Philip's death, Kate and Prince William shared a number of never-before-seen photos of Philip with their three children. First, accompanying Prince William's heartfelt tribute to his grandfather, was a sweet photo of Prince George sitting with his great-grandfather on a carriage.

The photo, taken in Balmoral Castle, shows a young Prince George holding hands with his father while a baby Princess Charlotte steals a glance at her great-grandparents, with the Queen smiling back at her.
