The Duke picked this book up at Value Village. "RAAF Log: The RAAF At War", published 1943 for the Royal Australian Air Force by the Australian War Memorial, Canberra, A.C.T.
A fantastic book, with beautiful colour plates (several examples below), line drawings, photographs, and stories. Clearly intended to boost morale on the home front. In the foreword, the Chief of the Air Staff writes, "we all have vitally essential parts to play whether it is flying a Spitfire or cleaning a kitchen, and it is up to us to serve our King and country with a whole-hearted honesty of purpose and cheerfulness at all times."
