This illustrated sheet is a Japanese-language civil-defense or propaganda leaflet from the Second World War, not a photograph. It depicts American four-engine bombers dropping ordnance on a burning city, accompanied by Japanese text warning residents about air raids. Ephemera of this kind was distributed on the Japanese home front to prepare civilians for Allied bombing campaigns. Though catalogued alongside material relating to the escort carrier USS Petrof Bay (CVE-80), the leaflet itself has no direct depicted connection to that vessel and was likely preserved as a wartime memento within the collection.
