This printed silk map of eastern Honshu, Japan, was part of the escape-and-evasion equipment issued to Allied aircrew during World War II. Lightweight, waterproof, and quiet to unfold, silk maps like this one could be sewn into flight jackets and used by downed airmen to navigate toward safety. Its association with the 345th Bomber Group at Ie Shima links it to B-25 Mitchell bomber crews who flew missions over the Japanese home islands in the final months of the war. Project: 218404
