Titanic artefacts to be auctioned

Almost 100 years after the Titanic ocean liner was sunk by an iceberg on her maiden voyage to New York, artefacts retrieved from the ship are about to go on auction.

The items being sold range from fancy jewellery and accessories of the wealthy first class passengers to a waistcoat from one of the passengers on the lower decks.
