Princess Diana, who once dreamed of a fairy-tale future with then-Prince Charles, faced a reality that unraveled over time. Katherine Hanbury, a school friend from West Heath Girls’ School, is working with Gorringe’s auction house to auction off photographs and letters beginning July 7.

“She was completely hopeful,” Hanbury shared with Fox News Digital, describing Diana as a young woman full of dreams of marriage, children, and a happy life.

A Special Honeymoon Letter

A letter written by Princess Diana during her 1981 honeymoon with Charles is among the items set to be auctioned.

“Its wonderful being married — I think its safe to say after two months…!”

Diana wrote to Hanbury during their honeymoon in Scotland, expressing a joyful sentiment.

Memories of School Days

Diana was known for enjoying everyday activities and cherished domestic life. Hanbury recalls Diana’s delight in tidying rooms, organizing drawers, and engaging in sports like swimming and tennis.

“She was sporty,” Hanbury said. “We rode bikes, making noise and having fun. She was just a girl like any of us.”

Despite Diana’s early departure from West Heath, she maintained contact with Hanbury.

A Young Princess

Diana became engaged to Charles at a young age. Hanbury described the discovery through the press as unexpected, given Diana’s youthful nature.

“She seemed barely out of school,” Hanbury said, reminiscing about their time together.

The auction includes a letter known as “The Honeymoon Letter,” revealing Diana’s adaptation to royal life.

“Its a case of playing with grown-ups,” Diana wrote.

Reflections on Diana’s Role in the Royal Family

Hanbury believed Diana’s future was set within the royal family, thanks to her caring nature. Even in the spotlight, Diana’s genuine kindness remained evident.

“She was genuinely kind,” Hanbury stated, reaffirming Diana’s authentic character.

Different Paths, Shared Memories

Diana’s trajectory led her onto the global stage. Meanwhile, Hanbury continued her education and built a life of her own, always remembering her friend.

“I wondered what the future would hold for Diana,” Hanbury said, pondering Diana’s impact.

The challenges in Diana’s marriage led to a separation in 1992, followed by a divorce in 1996. Tragically, Diana succumbed to injuries from a car crash in Paris on August 31, 1997.

“It was unbelievably sad,” Hanbury recalled, describing the collective mourning.

Legacy and Public Sentiment

Hanbury hopes that her auction will introduce Diana’s authentic charm to a broader audience.

“She was the real deal,” Hanbury affirmed. “She was Diana.”
