A postcard sent from a passenger the Titanic has fetched more than £7,000 at auction.

Andrew Johnston, who lived with his family in Thornton Heath, sent the postcard to his dad from the ship as it left Queenstown, now Cobh in Cork, Ireland.

The 35-year-old was emigrating to Connecticut with his wife Eliza and their children William and Catherine.

The master plumber wrote to apologise he “had not time to write before we sailed”.

He continued: “We don’t get to New York til Wednesday next so I will write when we get there.”

But the ship famously hit an iceberg and sank on April 15, 1912. The bodies of the Johnston family were never found.

The postcard was addressed to William Johnston, Newmachar, Aberdeenshire and signed “your affectionate son, Andrew”.

The auction was organised by MacDonnell Whyte and was held at the Hilton hotel in Dublin on January 21.

The postcard was expected to sell for about £4,000 but reached €8,500, about £7,055.
