The April auction of more than 5,000 Titanic artifacts a century after the luxury liner's sinking has stirred hundreds of interested calls.
Auctioneer Arlan Ettinger says his New York auction house has heard from some descendants of more than 700 survivors, including one offer he describes as morbid: papers from the body of a passenger found floating after the ship sank.
The Guernsey's Auctioneers & Brokers sale April 1 will offer a more poignant item: a children's bracelet with the name Amy spelled out in diamonds.
The auction involves clothing, fine china, gold coins, silverware and a 17-ton section of the Titanic's hull from the ocean floor.
The ship sank on its maiden voyage on April 15, 1912, after hitting an iceberg.
