This is my mother's mug from when she was a little girl. I believe it was made in the 1950s. They put milk in it to go along with Santa's cookies and left it out for him on Christmas Eve.
I too used to leave a treat out for Mr. Claus as a child. One year, my father plucked a white hair from his chest and placed it next to the napkin full of crumbs. When I woke up Christmas morning, he told me that Santa had eaten the cookies and there was the evidence (he accidentally left a hair from his beard!) While some may find this disturbing, I thought it was magical. :)
I hope you all had a wonderful Christmas. The holidays absolutely flew by me this year, but I still enjoyed the time with my family.
