Hey, let's not waste this opportunity!
Since we're on the subject of Christmas and War - check out these WWI Christmas cards.
Not much love for the fellow man noted...I especially love the aerial bomb Merry Christmas present, and the shooting star, i.e. a rocket lighting up the sky, so the machine gunners can have a pretty clear sight of the Huns on Christmas Eve!
The Russian card is kinda cute - "Our hero is home just in time for the holidays, sporting his medals". The little boy is a Full Cavalier of the Cross of St.George, Imperial Russian highest enlisted man's honor. Wounded, but very lightly.
