I have digged out a book from the heritage of my grandfather and scanned some photo's.
I remember that when my family stayed in the big house of my grandparents during the summer vacation I was always happy to go to bed!
I took the book from the shelve and read breathless about the heroic pilots between both wars.
I could not find the photo on the web by image search.
But character recognition on the 5 chaps in the foreground might be possible?
