Tucked among a family's wartime letters, this humble scrap of paper — likely the back of an envelope, marked with a few pencil notations — offers a small, human glimpse into the everyday habits of a serviceman or his correspondents. Preserved for decades in a wooden keepsake box alongside personal letters, artifacts like this remind us that history survives not only in dramatic photographs, but in the small, unremarkable traces people leave behind.
