Occussi-Ambeno issued this attractive set of stamps in 1998 to mourn the death of Princess Di. Here is the full set.

Mint unhinged, and in pristine condition.

In the early hours of 31 August 1997, Diana, Princess of Wales, died from the injuries she sustained in a car crash in the Pont de l'Alma tunnel in Paris. Her partner, Dodi Fayed, and the French driver of the Mercedes-Benz W140, Henri Paul, were pronounced dead at the scene. Their bodyguard, Trevor Rees-Jones, survived the crash but was seriously injured.

• Some media claimed the erratic behaviour of paparazzi following the car, as reported by the BBC, had contributed to the crash. In 1999, a French investigation found that Paul, who lost control of the vehicle at high speed while intoxicated by alcohol and under the effects of prescription drugs, was solely responsible for the crash. Anti-depressants and traces of an anti-psychotic in his blood may have worsened Paul's inebriation. In 2008, the jury at a British inquest returned a verdict of unlawful killing through grossly negligent driving by Paul and the following paparazzi vehicles. Some media reports claimed Rees-Jones survived because he was wearing a seat belt, but other investigations revealed that none of the occupants of the car were wearing their seat belts.

Diana was 36 years old when she died. Her death caused an unprecedented outpouring of public grief in the United Kingdom and worldwide, and her funeral was watched by an estimated 2½ billion people. The Royal Family were criticised in the press for their reaction to Diana's death. Public interest in Diana has remained high and she has retained regular press coverage in the years after her death.

• Since February 1998, Fayed's father, Mohamed Al-Fayed, has claimed that the crash was a result of a conspiracy, and later contended that the crash was orchestrated by MI6 on the instructions of the Royal Family.
