The advert has three names written on the back of it and some faded writing saying, 'This grave was opened on May 11 1913.'
The historians believe three stonemasons were doing repair work on the cathedral in 1913 when they disturbed a grave. They do not think there is relevance in the theatre advert, but that it was the closest piece of paper to hand.
The bottle which was discovered in the grounds of Durham Cathedral has finally been opened. Inside was an advert for a theatre production of English dance and folk songs at The Globe Theatre in London, Shaftesbury Avenue. The advert is dated 1913.
