LONDON (REUTERS).- The family of Princess
Diana
will auction a painting by Flemish master Peter Paul Rubens as part of a

clear-out sale valued at $30 million designed to ensure the financial
future of
the Althorp estate. Earl Spencer, Diana’s brother, is head of the
estate, and
plans to marry for a third time later this year, according to newspaper
reports. Diana, who was married to heir-to-the-throne Prince
Charles,
was killed in a car crash in Paris in 1997. The highlights of a
collection
including paintings, furniture, porcelain and horse-drawn carriages are
works by
Rubens and 17th century Italian master Il Guercino.
