This is a Thomas Bavaria platter in pattern 3816. The pattern doesn't have a name, just a number. The platter is white in the center with a wide yellow rim and a floral band around the rim with scrolls and gold trim. It is 15 1/4" wide, in very good to excellent condition. There are no chips or cracks, but there are some utensil marks. I also have a set of eight dinner plates listed in this pattern. The backstamp is green and reads Thomas Thomas Bavaria. This mark dates to 1933.
