New York: George H. Doran, 1926. First Edition of what is conceded to be one of the best contemporary accounts of that early aerial conflict. Illustrated by Clayton Knight. A fine copy in a very good or better dust jacket with minor wear and tear, and a small exterior tape mend at the top of the back panel. The first blank is presented (signing as “Elliott Springs”), enhanced by an excellent, large color drawing of a dogfight, signed and inscribed to the same recipient by the illustrator. While Knight enjoyed a successful career as an illustrator, primarily of aviation, he might now be more renowned as the father of Hilary Knight, illustrator of the Eloise books.
