This, for me, is sort of like a Christmas tree. The sneakers are mostly tacky ornaments, but the overall, collective effect is quite festive.
So you’re probably thinking since I compared the first one to a Christmas tree, that this one must be the crèche. Which would make Mary and Joseph headless bike messengers, and the baby Jesus the World Cup soccer ball whose suspect design has all the losers whining in their foreign equivalent to Wheaties. But no. It’s just an ugly, chaotic window display. Also, headless Joseph is wearing basketball(?!) sneakers.
