WW I and WWII Sweetheart Pins

These are various Sweetheart pins I have collected. I think my favorite is the 3 star pin with the caduceus. These pins used one star for each family member in the service. A 3 star pin really brings home the sacrifice people were making to maintain our way of life. The second pic is of 2 celluloid pins I found at different times, One says Son in the Service, one says Husband in the service. Thanks, Veterans!
