Original US WW2 Paratrooper Airborne invasion arm flags. These were obtained, well over 20 years ago, from a former WW2 US 3rd Army quartermaster NCO who was involved in the procurement of arm flags for the upcoming invasion of Europe by the US. They are made of a silk like material with finished sewn edges and measure 5 1/2 inches by 4 inches. All are in perfect condition.

I have added a photo of the reverse, as requested.
