Being a soldier deployed in World War II, or any war at that, is one of the most stressful things a man can experience. Not only is he far from his family, he also is uncertain if he will return home from the battlefield alive. To keep themselves close to the people they left as they went to the battlefield, soldiers back in those days would put pictures of their families or sweethearts on clear grips. These grips would then be known as “sweetheart grips”.
