A postcard from a worker on the Titanic could sell for $15,000 at an auction. The card was written by the ship's wireless operator Jack Phillips. He wrote to his sister while the Titanic was at port. He wrote: "Very busy working late. Hope to leave on Monday and arrive in Southampton Wednesday afternoon." His message ends with the words, "Love, Jack." The postcard has photos of the Titanic on one side. On the address side of the card there is a postmark from a post office in Belfast. The card is one of many things from the shipwreck of the Titanic in a multi-million-dollar auction.

The Titanic was completed in 1912. Its builders said the design meant it could not sink. It started its first voyage, from the UK to New York, on April the 10th, 1912. It hit an iceberg in the Atlantic Ocean five days later. The impact made a big hole in the ship. More than 1,500 of the 2,224 passengers died. Mr Phillips escaped overboard as water flooded the ship. He sat on an overturned lifeboat and waited to be rescued, but he died of exposure to the cold. He was 25 years old. The story of the Titanic was made into a 1997 Oscar-winning movie starring Leonardo DiCaprio.
