Hello,
I bought this book - in Dutch - a couple of weeks ago. It is part 1 of the history of aviation above Gent. In this book there is of course a lot of info on WW1: the story of the attacks from Zeppelins, Gotha's and Riesenflugzeuge on England and the counterbombardements by the British. There are also many photo's from planes and pilots.
A very interesting book. Highly recommended.
