The following BBC news item from Staffordshire contains one comedy gem... https://www.bbc.co.uk/news/uk-england-stoke-staffordshire-64891310 The line in question is " The cup was not on the liner when it sank on its maiden voyage in April 1912 ...." No sh*t Sherlock!! (unless it miraculously transported itself into a Burton on Trent kitchen cupboard from the icy depths of the Atlantic ocean ). The article also says "The cup is believed to have been made more than 100 years ago, auctioneer Charles Hanson said." ....Well not really a surprise since the pattern R4332 was created for 1st class passengers for a ship which sank in 1912. Whilst a similar pattern R4331 was used on the sister ship vessel Olympic, the R4332 was exclusive to the Titanic, and also presented as a company gift or possibly sold as White Star Line souvenirs to wealthy passengers. Pieces of the distinctive R4332 ceramic are known to have been recovered from the wreck of Titanic.” Highly improbable given its fate that they would have continued to make them for another 10 years or more after the disaster
