Santa & Rudolph Vintage Coffee Mug

This cute little vintage mug has a printed image of Santa and his sleigh being pulled by Rudolph and the eight reindeer flying over houses. They are in brown and the houses are in green. There is a matching green band around the lip of the mug. Measures 3.25" high and holds 6 oz. This mug is unmarked and no idea of actual age or origin, but have never seen another like it. In great condition.
