The Boeing B-17 Flying Fortress is one of the most renowned U.S. bombers ever produced. Its combination of maneuverability, range, and heavy load capability made it the backbone of the 8th Air Force's strategic bombing campaign during World War II. B-17s flew in formations designed to protect the airplanes and their crews while maximizing firepower. Our genuine leather bifold wallet pays tribute to the B-17 with a printed graphic motif designed to represent a B-17 flying formation. It has a 100% cotton lining to protect credit cards and cash. Black. Measures 12 cm W x 8.90 cm (folded). Imported.
