You can see the photo and read the full story here.

Prince William joins the large number of people who have been pinning photos of their grandparents on Historypin since its creation – there is even a popular “My Grandparents are Better than Yours” Collection.

Martin Luther King III is another celeb who has also pinned a photo of himself and his famous grandfather.

The photo the Prince pinned shows his grandmother, The Queen, at his graduation from Sandhurst. Remembering the moment the Prince wrote “I felt especially proud to receive my commission as an officer in front of my grandmother, The Queen. She has been an incredible role model to me over the years, so it was very special to have her present for my graduation.”

The Prince pinned the photo and memory as part of Pinning the Queen’s History, an interactive global archive of The Queen’s visits and Jubilee celebrations over six decades to mark the Diamond Jubilee.
