Blood chits were used by U.S. aviators as a way of communicating with non-English-speaking people. Made of leather, cotton, silk, or rayon, they served as a safe-conduct pass for a downed aviator in need of help from local people. This blood chit is printed with the U.S. flag and five languages. The fabric is stitched to a cotton backing fabric.
