David Gepp has been researching graffiti scrawled on the walls of the disused "Time Tunnel" of Llangollen, Wales.
David said: "When the tunnel was built, about 1864, it was lined with a type of tile that took pencil readily and local people took to writing their names or messages to loved ones.
"It soon became apparent that a great number [were] written by young men of the area heading off to the First World War, and it became a real obsession trying to discover who they were, and what fate befell them in the trenches."
The fading signatures scrawled on the tiled brick were a poignant reminder of the Great War, the first kindlings of romance and the unrefined humour of youth.
One message says "Berlin last stop", another is signed "Balls from Belgium", and a third the schoolboyish "Hoof Hearted". [Link]
