DEVIZES, ENGLAND - APRIL 15: Auctioneer Andrew Aldridge of auctioneers Henry Aldridge & son holds a letter from Wallace Hartley, the band leader of the Titanic written aboard the doomed liner, which is being auctioned this week, on the 101st anniversary of the sinking of the ship on April 15, 2013 in Devizes, England. The auction house, which specializes in Titanic memorabilia and is having an associated sale on Saturday, spent seven years proving the violin was genuine and belonged to Wallace Hartley, who with his orchestra, famously played on as the ship sank in April 1912, and were among the 1,500 who died. Long thought to have been either lost at sea or stolen, it is being described, as far as Titanic memorabilia goes, as one the most important pieces that has ever come up for sale. Thought to be worth a six-figure sum, it is the property of an unidentified individual in Lancashire and will be displayed to the public all week, but Aldridge's have not yet confirmed when it is likely to go on sale.
