It looks like one of the types of designs they have at "Trend-D" at downtown Disney. So, is there a shop like that somewhere in the Magic Kingdom? Maybe within the Main Street Emporium?
You have chosen wisely, it is on the side of the sleigh outside the Christmas shop. I actually found this looking for Tim's plate that was inside the shop!
I would not necessarily thought the sleigh because I thought it was red. (Looked at photo and it the runners and front end are red while the seats and sides are black.)
