3. David McLellan’s publicity photo used as a post card. I am grateful to Rainer Absmeier for providing me with this scan of the post card in his possession. The photo was reproduced in Thayer’s America’s First Eagles (captioned “British and American Pilots on the Western Front”) and more recently in Franks’s American Aces of World War I and Franks and Dempsey’s SE 5/5a Aces of World War I. In the last two, only the pilot on the right is identified (as “Lt. C. [sic] Hooper of the USAS”).
