This ornament features "Old Bill", an incredibly popular cartoon that was developed by war cartoonist Bruce Bairnsfather.
Bairnsfather served as a British soldier with a Machine Gun Unit during the Second Battle of Ypres in 1915, from which he was hospitalised with shell shock and hearing damage. He was then posted to the 34th Division on Sailsbury Plain. It was around this time that Bairnsfather came up with the character "Old Bill", for a series about life in the trenches. "Old Bill" featured in a weekly cartoon called 'Fragments from France' which was published by The Bystander.
