1. Pilots of No. 32 Squadron. This photo was taken by Ministry of Information photographer David McLellan and can be found at the Imperial War Museum in London (catalogue number Q 12041). The IWM description reads: “Pilots of No. 32 Squadron. An American, Canadian, New Zealander, Englishman and South African, respectively; Green, Lawson, Leese, McBean, Hooper. Humieres aerodrome, near St. Pol, 15 May 1918.” I believe the identification of the men, left to right, is correct, although the nationalities have been incorrectly assigned. Humières was about a mile northwest of Beauvois. Parr’s nose looks slightly crooked. Perhaps the effects of the crash mentioned in his letter of February 18, 1918, are visible here (although not in other post-crash photos).
2. Pilots of No. 32 Squadron. Another photo by David McLellan of the same men (IWM catalogue number Q 12042). This was slightly cropped and used as a publicity photo.
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”).
