Six stamps and a Miniature Sheet celebrate the 70th Birthday of HRH The Princess Royal. HRH Princess Anne was born at Clarence House, London, on 15th August 1950. The only daughter of HM Queen Elizabeth II and Prince Philip, Duke of Edinburgh, Princess Anne was created the Princess Royal in June 1987, a title that is traditionally carried by the British monarch's oldest daughter and held for life. Princess Anne began undertaking public engagements at the young age of 18. Since then she has built up a working relationship with many organisations and charities across the Commonwealth. Dedicated to many causes, and a sports enthusiast, HRH The Princess Royal has one of the busiest working schedules of all the Royal family members.
