I remember seeing photos of banners that were hung in windows of homes of families that had lost a loved one. It was small and had a gold star. Each star represented a loved one that died in the war.
The blue and gold star tradition began in WW 1 when white service flag bordered in red were displayed in homes, business, schools and churches to indicate, by the use of a blue star, each active service member in the US Military. A gold star would indicate those who gave their lives for the country.
Recently I started a book-A Star For Mrs. Blake. The book is about a group of gold star mothers who on the invitation of the US Government were offered a trip to France.
I was amazed. The government actually having a heart? I had to look it up and see if this actually happened.
