Queen's stamps on public display

One of the world's finest collections of postage stamps -- belonging to Queen Elizabeth -- is going on public display today for the first time.

The collection, which is worth nearly one-hundred-and-fifty million dollars, includes one of the world's rarest stamps -- the Post Office Mauritius Tuppenny Blue, of which the only four known surviving examples are valued at three million dollars each.

Tight security will be in place at the central London venue the Earls Court Exhibition Centre where the collection will form the focal point of the week-long Stamp Show Two-Thousand.
