Titanic price tag for White Star poster
A rare poster advertising transatlantic trips on Titanic and her sister ship, Olympic, is expected to sell for at least £6,000 when it is auctioned in America later this month.
The poster, featuring the words 'White Star Line, RMS Olympic & Titanic, largest steamers in the world', was produced in or around 1911.
It came just a few months before one of the world's worst maritime disasters.
More than 1,500 people died after Titanic hit an iceberg and sank on April 15 1912, during her maiden voyage from Southampton to New York.
The Titanic-Olympic poster is set to fetch between $8,000 and $12,000 (£6,000 to £9,000) at Swann Auction Galleries in New York on October 26.
Although the poster features an image of Olympic, it is the references to Titanic which make it so valuable.
Both ships were built by Harland and Wolff in Belfast.
When Swann Auction Galleries sold a similar Titanic poster in November 2015, it fetched £8,000.
The Titanic-Olympic advert is by James Scrimgeour Mann, who was born in Dundee in 1883.
Mr Mann inherited his enthusiasm for the sea from his father, James Mann senior, who was captain of a Dundee ship and died at sea off the coast of South Africa in 1901.
Also going under the hammer on the same day is a 1926 poster advertising Northern Ireland as a tourist destination.
It was commissioned by the Ulster Transport Authority and emblazoned with the words: "Salmon Fisheries, Northern Ireland."
It is expected to fetch between $700 and $1,000 (£500 to £750).
