Warren's prisoner ID card and POW dog tags from Stalag Luft I . Interesting note. My father told me he flew with his flannel pajama shirt under his flight suit that day (it was cold and he was in a hurry). When he was captured they took his flight suit and gave him the coat you see in this picture to wear for the photo. Because he did not have a dress shirt on, they wrapped a scarf around his neck which you can see in this picture.
