A postcard from the Titanic could sell for $15,000. It was written by a ship worker, Jack Phillips. He wrote it to his sister. The postcard has photos of the Titanic on one side. On the address side there is a postmark from a post office in Belfast. The card is one of many things from the Titanic for sale in the auction.

The Titanic was built in 1912. Its builders said it could not sink. It sailed for the first time on April the 10th, 1912. It hit an iceberg five days later and sank. More than 1,500 passengers died. Mr Phillips escaped. He waited to be rescued, but he died from the cold. He was 25 years old. The story of the Titanic was made into a movie.
