Vintage Korean War Era Red Cross Flag 2x3, Hand Stitched, Unbranded

Up for sale is a Korean War era Red Cross field hospital flag in good condition. The flag has no brand stamp and appears to be "hand stitched" with a sewing machine because you can see the irregular stitching not seen on machine assembled flags. It also appears that the Red Cross has been applied like a patch over a cut out in the linen and not woven into the fabric. I have some Keystone Red Cross flags currently listed and those are well marked with very different types of construction compared to this one. The original owner was an Airborne and due to a bad training jump, spent lots of time in a field hospital with 2 broken legs. That's where he acquired the flags. Once he came back home to the states, the flags spent all of there time in a cardboard box in the basement of his home.
