A postcard from Northern Ireland written by the Titanic's senior radio operator just weeks before the ocean liner sank in the North Atlantic in 1912 has been put up for auction.
The card, with a glossy image of the ill-fated ship on the front, was written by Jack Phillips to his sister, Elsie Phillips, in March 1912 while awaiting the ship's first sea trials, according to RR Auction in Boston.
"Very busy working late. Hope to leave on Monday & arrive Soton Wednesday afternoon. Hope you quite OK. Heard from Ethel yesterday," he wrote.
The postcard is signed "Love Jack."
It is postmarked Belfast, where the Titanic was built, and has a cancelled halfpenny stamp.
"Soton" is a contraction of Southampton, the English port city from where the Titanic departed on its maiden voyage.
It sank in the early morning hours of April 15.
Phillips, who turned 25 on board, stayed at his post after the Titanic struck an iceberg to send calls for assistance to other ships in the area until water was lapping around his feet, according to RR Auction.
He made it off the ship after being told by the captain that he had done his duty, according to his biography in the British National Archives, but died of exposure in the frigid North Atlantic, according to RR Auction.
The postcard is being sold by the estate of Vera and John Gillespie, longtime members of the Massachusetts-based Titanic Historical Society, said Bobby Livingston, executive vice president at RR Auction.
It is expected to sell for around $15,000 (£11,000) in the Fine Autographs and Artifacts auction that began on March 26 and ends tomorrow, the day before the anniversary of the tragedy.
Titanic memorabilia is still popular, more than a century after the disaster, he said.
"It's one of those stories that still resonates around the world, about the hubris of man being taken out by nature," he said.
Last month, a letter reputed to be the last written on board the liner went on display in the Titanic Belfast centre.
The historic artefact, written by a mother and daughter who survived the ship's sinking, was never sent and was recently bought by a Scottish couple for almost £120,000.
Edinburgh businessman Garreth Wood and his wife Nicola, both long-time Titanic enthusiasts, have loaned the letter to Titanic Belfast.
