Personal notebook of 1st Lt. Robert Porter, 3x5", in which he recorded extensive information on 76 pilots, observers and staff of the 11th Aero Squadron. Information includes dates of service, colleges, home town, nicknames, training, number of raids, etc. Most interesting are annotations such as "ship number", "KIA as per leaflet dropped by Hum Plane", "Missing", "P.O.W.", "One official Boche shot down in flames", "Died in hospital with broken back", etc. Very good, easy-to-read ink printing.
