Question: Which other other major ocean liner for the British Cunard Line preceded the ocean liner that was featured in a book of photographs by Philip Plisson?

Context paragraphs:
SS Île de France: The SS "Île de France" was a French ocean liner built in Saint-Nazaire, France for "Compagnie Générale Transatlantique".  The ship was the first major ocean liner built after the conclusion of World War I, and was the first liner ever to be decorated entirely with designs associated with the Art Deco style.  It was neither the largest ship nor the fastest, but was considered the most beautifully decorated built by CGT (also known as the "French Line") until the "Normandie" .

SS Ivernia: SS "Ivernia" was a British ocean liner owned by the Cunard Line, built by the company Swan Hunter & Wigham Richardson of Newcastle upon Tyne, England, and launched in 1899.  The "Ivernia" was one of Cunard's intermediate ships, that catered to the vast immigrant trade.  Together with her sister ship SS "Saxonia", the "Ivernia" worked on Cunard's service from Liverpool to Boston and then later on the immigrant run the Cunard Line had established from Fiume and Trieste to New York City.

Four funnel liner: A four funnel liner, four funnelled liner or four stacker is an ocean liner with four funnels.  The SS "Great Eastern", launched on 31 January 1858 (a full 40 years ahead of any comparable ships), was the only ocean liner to sport five funnels.  As one funnel was later removed, the "Great Eastern", by default, became the first ocean liner to have four funnels.  However, after the Great Eastern became a four funnel ship she never carried passengers so really should not be considered the first four funnel liner.  The SS "Kaiser Wilhelm der Grosse", launched on 4 May 1897, was properly the first ocean liner to have four funnels and was one of the first of the golden era of ocean liners that became prominent in the early- to mid-20th century.  The most famous four funnel liners are the RMS "Titanic", which sank after striking an iceberg on her maiden voyage on 14 April 1912, and the RMS "Lusitania", which was torpedoed on 7 May 1915 during the First World War.

RMS Queen Mary: RMS "Queen Mary" is a retired ocean liner that sailed primarily on the North Atlantic Ocean from 1936 to 1967 for the Cunard Line (known as Cunard-White Star Line when the vessel entered service).  Built by John Brown & Company in Clydebank, Scotland, "Queen Mary", along with  , were built as part of Cunard's planned two-ship weekly express service between Southampton, Cherbourg and New York.  The two ships were a British response to the express superliners built by German, Italian and French companies in the late 1920s and early 1930s.  "Queen Mary" was the flagship of the Cunard Line from May 1936 until October 1946 when she was replaced in that role by "Queen Elizabeth".

RMS Aquitania: RMS "Aquitania" was a Cunard Line ocean liner designed by Leonard Peskett and built by John Brown & Company in Clydebank, Scotland.  She was launched on 21 April 1913 and sailed on her maiden voyage to New York on 30 May 1914.  "Aquitania" was the third in Cunard Line's "grand trio" of express liners, preceded by RMS "Mauretania" and  , and was the last surviving four-funnelled ocean liner.  Widely considered one of the most attractive ships of her time, "Aquitania" earned the nickname "Ship Beautiful".

Philip Plisson: Philip Plisson (born January 27, 1947, Orléans, France) is a French photographer best known for his maritime photography.  Together with his son Guillaume, who is also a photographer, he set up the publishing company Pêcheur d'Images.  He has produced numerous books including collections of photographs featuring Brittany, Ireland, Scotland and the ocean liner "Queen Mary 2".  His 65th book, "Les Marées", was named Maritime Book of the Year at the 2012 Paris Boat Show.

RMS Queen Mary 2: RMS "Queen Mary 2 (also referred to as the QM2") is a transatlantic ocean liner.  She is the largest and only major ocean liner built for the British Cunard Line since "Queen Elizabeth 2" in 1969, the vessel she succeeded as flagship of the Cunard Line.

Queen Elizabeth 2: Queen Elizabeth 2, often referred to simply as QE2, is an ocean liner built for the Cunard Line which was operated by Cunard as both a transatlantic liner and a cruise ship from 1969 to 2008.  She was designed for the transatlantic service from her home port of Southampton, UK, to New York, and was named after the earlier Cunard liner  .  She served as the flagship of the line from 1969 until succeeded by  in 2004.  Designed in Cunard's then headquarters and regional offices in Liverpool and Southampton respectively, and built in Clydebank, Scotland, she was considered the last of the great transatlantic ocean liners until the construction of the Queen Mary 2 was announced.

Sagafjord: MS "Sagafjord was an ocean liner built in 1965 by Société Nouvelle des Forges et Chantiers de la Méditerranée for Norwegian America Line as the combined ocean liner/cruise ship.  Between 1983 and 1996 the "Sagafjord" was operated by Cunard Line.  In 1996—1997 she was briefly operated by Transocean Tours as MS "Gripsholm prior to being sold to Saga.  She was lastly owned and operated by Saga Cruises on worldwide cruises targeted at the senior market out of the United Kingdom, known as the MS "Saga Rose" .  She was retired from service in October 2009.

RMS Niagara: RMS "Niagara" was an ocean liner launched on 17 August 1912 and owned by the Union Steam Ship Company intended for the Australia-Vancouver, Canada service.  She was nicknamed "the "Titanic" of the Pacific", but after the sinking of the real  this was dropped in favour of "Queen of the Pacific".  She should not be confused with an earlier RMS "Niagara", an ocean liner built in 1848 for the Cunard Line.
