A previously unseen letter written by the late Queen Elizabeth, reflecting on her "very hectic" schedule as a young mother, has resurfaced after 77 years. The letter, dated 4 November 1949, was written by then-Princess Elizabeth to Peter Stewart, a trusted member of the royal circle and secretary of The Carlton Club, a prestigious London gentlemen's club. In the letter, she expressed her struggles in keeping up with her duties and personal life, saying, "I completely fail to keep up with the things I have to do." At the time, she was 23 years old and had recently become a mother to her eldest son, Charles, who had just turned one. Elizabeth also apologized for not replying to Stewart's earlier letter, explaining that life had become "very hectic." She admitted to being unhelpful in choosing Christmas gifts for her family, saying, "I am most unhelpful for I never know what my family could possibly want." The two-page letter was handwritten on paper with a Clarence House letterhead and signed "Elizabeth." It is now being offered for sale at Chiswick Auctions in West London, with an estimated price of £800 to £1,200. Manuscripts specialist Valentina Borghi described the letter as a "really nice" artifact, noting that items related to young Princess Elizabeth are rare and highly sought after by collectors. She explained that Peter Stewart was a close confidante of the royal family, including King George VI, Queen Mary, and later Queen Elizabeth II and Prince Philip. Stewart was often seen at Clarence House and played a key role in helping the royals choose and acquire gifts for each other. In November 1949, Princess Elizabeth was in London for a series of public engagements, including the Royal Variety Performance at the London Coliseum on November 7. She then traveled to Malta to join her husband, Prince Philip, before returning to London to celebrate Prince Charles's first birthday. She left London again on November 20 for Malta. This period was particularly busy for Elizabeth, who was balancing royal duties with her new role as a wife and mother. Additionally, her father, King George VI, had recently undergone surgery, which likely influenced her desire to stay close to her family and support her father during his recovery. The letter will be auctioned on 27 September. Queen Elizabeth II passed away in 2022 at the age of 96, leaving behind a legacy that continues to be explored and cherished by the public and collectors alike.
