The most expensive Titanic artefact ever sold at auction, regarded as the 'Holy Grail of Titanic memorabilia', is the 33-foot wide (10m 05cm) Indian ink and colour washed plan currently on display at Titanic Belfast.
The plan was prepared by White Star’s Naval Architects’ Department for use at the Wreck Commissioner’s Court of Inquiry into the loss of Titanic in order to assist witnesses and members of the Court during the Inquiry.
Like a world in miniature, Titanic’s longitudinal plan contains a wealth of detail. For example, a few minutes spent studying the layout of the 3rd Class passenger accommodation reveals another inbuilt problem - how do these passengers reach the Boat Deck in an emergency?
