Back in the late 90's I had the pleasure of helping to develop the Christmas window display for Macy's Herald Square in NYC. It was based on a sweet little animated short from "Mickey's Once Upon a Christmas"
I went to Florida on behalf of Disney and worked with the fabricator (Creative Arts) who did a fantastic job on the whole thing. I lost the original drawings long ago but I recently found these photos online of the finished windows. It was really fun and dare I say magical.
Keep in mind that most of the characters were animated with simple movements so you can imagine the budget on this thing....man, those were the days.
