By Lawrence L. Smart, 1st Lieut. 135th Aero Sqn. USAS.
I picked this book up in a second hand bookshop recently. It's softback with 70 A4-sized pages and printed in a font just like that of an old typewriter.
It covers the author's experiences of training and combat and includes photos of people and aeroplanes that, mostly, appear to be the author's own photos.
Unfortuntely there is no ISBN, no date of publication or even the name of the publisher anywhere on the book.
