​Markings: Depicts Victor 89 on the fuselage alongside the circled 'R' on the vertical stabilizer. The 509th Composite Group temporarily painted the markings of other groups (in this case, the 6th Bombardment Group's circle-R) on their tails right before the combat missions to mislead Japanese observers.

​Provenance/Inscriptions: The reverse displays contemporary serviceman handwriting reading "At. bomb - nagasaki" and a wartime darkroom/processing contact number "249
