You can see it’s taken from a photo album. I cropped, sharpened, and contrasted it a bit to bring out the details of the contrails. The text “Note Little Friends” probably refers to the fighter escorts making curved contrail in the background.

It looks similar to this more famous photo:

That’s know as “Top Cover for the J Group”, and is detailed here. This photo was also taken over Emden, on September 27th, 1943, by Stanley M. Smith. Given the weather, and the planes involved, it might well have been taken on the same mission, within a few minutes of the first photo.
