Most famous for their use by the pilots of the Flying Tigers and the aircrews of the "Hump" long-haul logistics pipeline, the blood chit was a way for foreign pilots, who often lacked local language skills, to seek civilian aid in the event of a bail-out or forced landing. In short, the chit informs the reader that the person carrying it is an ally of China, and requests their help returning them to Nationalist authorities. Seen in multiple patterns, this chit measures about 9 inches tall and 10 inches wide, with the top half filled with American and Nationalist Chinese flags, and the text below. No markings are present on the back, or any stamps or seals. The Nationalist flag is decorated with a set of gold bullion embroidered wings accented with a Nationalist star. Provenance: The Putnam Green/Sycamore Collection

Good overall, with mild scuffs and stains, and a small tear in the lower right section of the chit.
