The fascinating five-page booklet was produced exclusively for first-class passengers.
The front cover is dominated by a picture of the awe-inspiring liner dwarfing other vessels.
Inside, one page is devoted to the Louis XVI Restaurant where a la carte meals were served till 11pm, while another showcases the Cafe Parisien, setting of choice for late-night card games.
The upmarket restaurant reception, with its pillars and mahogany tables, was designated for afternoon tea, while well-to-do travellers could unwind in the lavish Turkish bath room which “rivals anything similar to be found in London, Paris or New York”.
Just 325 first-class passengers were able to make the most of these opulent surroundings out of the 2,208 passengers on board.
The brochure is being sold for an estimated £8,000 along with an equally scarce ticket for the launch of the Titanic in Belfast on May 31, 1911 – 11 months before it hit an iceberg and sank with the loss of 1,522 lives.
There were just 705 survivors.
The VIP ticket is tipped to sell for £25,000.
The items are being auctioned on Saturday week in Devizes, Wiltshire.
Auctioneer Andrew Aldridge said: “Both the brochure and ticket are exceptionally rare.”
Of the ticket, he said it was only one of a handful to have survived with its stub.
He added: “It is a truly exceptional piece of Titanic and Belfast history.”
