Historically, the Blue Star flag is hung in the window to show that the home has an immediate family member serving in the military. Also known as the War Mother's flag or Service Flag, the blue stars were sewn over in gold if the hero wasn't expected to return. This is a tradition that started during WWI. Her Hero's version of the service flag is vibrant pewter and hangs from a sterling silver box chain, accompanied by a feminine freshwater pearl. Blue Star Flag Informational cards are also included.
