Italians were not enthusiasts of the Christmas card craze early in the 20th century but I do have two examples from their country as it participated in World War I.
The first is a rather harmless attempt to evoke seasonal jollity by pairing children and a piece of artillery.
The second is more heart-felt. It shows an Italian woman in chains, presumably a metaphor for those of Italian stock languishing under the rule of the Austro-Hungarian empire, and a charge by the famous feather-helmed Bersaglieri infantry. Above them an angel signals divine approval of the war effort and the caption reads “Christmas of glory”.
