This helmet is from a man who fought in the Vietnam War. My father bought it in Portobello market when he was 10, for £7. This object was used to protect the soldiers' heads during battle.

It is a helmet that was worn in the Vietnam war. We do not know who exactly wore it. It was worn by infantry men. It still has a joker card and peace symbol on the outside.

Truth be told, troops in Vietnam didn't "get away" with writing on their issued helmets, and neither do the troops who do it today.
