After the mysterious postcard, depicting a reindeer and painted by an artist active during the 19th century, turned up among bills and other more mundane mail, the mortgage association took to social media in search of details about the addressee:
"Do you know anything about Lydia Davies, who lived on Craddock Street in 1903 (according to the postmark)?
We want to make sure it ends up where it belongs, whether it's the local archive or possibly Lydia's surviving family, says the mortgage association's communications manager Henry Darby to Sky News.
A relative of Lydia Davies is said to have contacted the mortgage association after the appeal.
According to a spokesperson for the British postal company Royal Mail, it is more likely that the postcard has been reposted by someone rather than having been lost for over a century.
