Trench Art transformed whatever scrap metal littered the so-called No Man's land, as well as behind the lines. It was born out of the troops' need to keep themselves busy during the longs lulls between deadly attacks. Brass cannon shells were transformed into vases for dried flowers and sent home to loved-ones. Vast quantities of rings, bracelets, letter openers, desk accessories, matchbox holders, ashtrays and lighters were also created.

At the end of the War, those living around the devastated battle-grounds crafted commemorative vases and other mementos, which were brought back home by veterans. Some of the surpluses from ordnance factories were also made into personalized souvenirs.
