Question: You discover that one of your deceased relatives earned medals during both the Second World War and the Korean War and you are very proud of your relative’s contribution to his country. They have been given to you by inheritance. They are in perfect condition. How would you be able to display them while not damaging them to the elements (to the environment)? . (.
