One of few photos I have of my grandfather in uniform is with his ~6 month old son and wife. While editing a digital version of the photo, I noticed that his son, my uncle, was wearing a ring on his wedding finger. Was this a common practice during WWII? I have read that the trend for men to wear rings, especially wedding rings, changed during this time period and became the new norm. Was it a simple reminder/ward to "wondering eyes" of men to indicate that my grandmother is married, and this child has a father? Was this common practice during the period or was it simply something that my grandmother thought up and implemented?
