Cuddling The Christmas Clogs - 3 French 1900s Christmas Postcards

Actually what IS going on here ...?
Well...According to tradition, on Christmas Eve children leave their shoes by the fireplace filled with carrots and treats for Père Noël's donkey, Gui (French for "Mistletoe") before they go to bed. Père Noël takes the offerings and, if the child has been good, leaves presents in their place. In the clog. Obvious really.
There is a written greeting on the back of 2 of these postcards - see last photo.
One postmark clearly shows 1904.
