A letter written by Diana, Princess Of Wales three weeks before her death sold for $3,840 (£2,400) at an auction on Monday (28Apr14).
Her last official note, penned on Kensington Palace-headed paper, was to landmine campaigner Dilys Cheetham, thanking her for her work for the cause.
She also told Cheetham she was "deeply moved" by a recent trip to Bosnia and pledged to continue supporting anti-landmine charities.
It was dated just three weeks before the Princess Died in a car crash in Paris, France on 31 August, 1997.
The letter was bought by a private buyer for $3,840 at Fellows Auctioneers in Birmingham, England.
