Previously unseen private family photos of the late Princess Diana and then-husband King Charles III as young parents with their then-baby boy Prince William are set to be put up for auction next month.

The pics also feature Queen Elizabeth II. They were taken in September 1982, when William, the new Prince of Wales and heir to the throne, was about 3 months old, and two years before his brother Prince Harry was born.

The photos also show the family with their friend John King, Baron King of Wartnaby, a British Airways official.

The pics, along with their original negatives, will be auctioned by Willingham Auctions in Cambridge, UK on March 4.
