This is a beer badge worn by hippies and others who were involved in anti-war activities during the Vietnam War.
This item is decorated with the peace symbol used as a symbol of peace, and is a part of the culture of the time. Soldiers of that time dared to wear this kind of item, and recently, there are people who wear it as a fashion item. I think this item can be used in various ways, so you can still enjoy it. One of the pins on the back is missing and needs to be repaired. Please consider that it is an old item and fragile. This is a used item and cannot be returned.
