This is a detail from a more old fashioned Christmas window type decoration. Those skiers and that ski lift are mechanical and they are in constant movement.
I have some things I need to shoot uptown tomorrow. Maybe I will walk up 5th Avenue and take pictures of all the elaborate windows I pass by. I just remembered that Barney’s always had great Christmas windows (they used to be right nearby me, now they’re uptown so I haven’t seen their windows in a while). I forget where they are exactly, I wonder if they will be on my way?
