More than a century after the Titanic went down, so goes the company that owns 5,500 artifacts from the doomed ocean liner.

As part of its bankruptcy proceedings, Premier Exhibitions is auctioning off its gigantic collection of Titanic artifacts, to be held at Troutman Sanders' Atlanta headquarters at 10 a.m. on Oct. 11.

Troutman is bankruptcy counsel for RMS Titanic, a Premier Exhibitions subsidiary that is the exclusive steward of the ocean liner's wreck site in the North Atlantic. The Titanic sank on its maiden voyage on April 15, 1912.
