The note was written by John P Schulte, who called himself the first flying priest. The note requested that the carnations and crucifix be placed on the grave of his brother, Lieutenant Franz Schulte, who had died of Spanish flu during the deadly influenza pandemic of 1918, as a Prisoner of War at Raikeswood Prisoner of War Camp, Skipton, originally built as a training camp for the Bradford Pals, in 1915. Schulte was, at that time, buried at Morton Cemetery east of Keighley (though the letter states he is buried at Skipton, this was incorrect).
