Prisoners of War (POWs) in Vietnam were given tin mugs. This was one of the only items that they could claim ownership of in detention. Mugs like this were used for food and for means of communication. POWs would hold their mugs against the walls of their cells to amplify the tap codes from other prisoners - which was their only means of communication. 

Learn about this and other POW experiences in our exhibit, Life Behind the Wire: Prisoners of War.
