Postcard from the USA!

Today I got a cool postcard from the USA! The postcard shows the Service Flag of the United States. The Service Flag is a banner that can be displayed by the families of those serving in the Armed Forces during any time of war or hostilities. Their use is authorized by the Department of Defence and they were first used unofficially during World War I. Also called blue star banners, they were displayed as a sign of having a child serving in the war. The postcard is an official Postcrossing card, US-3083815. Thanks Jennifer!
