I love the velvet costumes of these two Santas. They remind me of the shepherd's costume Mother made for me for my 6th grade Christmas Pageant. http://livingthelifefandango.blogspot.com/2011/11/vintage-christmas.html
Prior to the circa 1880s or so, Santa Claus was Father Christmas, or the Spirit of Christmas, and wore green, not red. He had trappings of the old pagan god, An Dagda, complete with holly (the sacred red and green) and the magic cauldron (the horn of plenty). You will see the real Father Christmas in any good version of Dicken's A Christmas Carol.
