The letter, written by first-class passenger Archibald Gracie, sold for five times its expected price at auction. It was written aboard the ship five days before it sank.

Col. Archibald Gracie wrote the letter while traveling on the Titanic days before the ship sank and plunged him into the icy North Atlantic.
