I think the REAL question is; what do you display? It's a full animated billboard, you're not just going to display a still image of her. You'd probably have to rent it for at least an hour so you'd have plenty of time to display pretty much anything she's done (you'd probably have to contact Cover corp and get written permission to relay to the signholder for liability/copyright) so what is THE iconic Fubuki clip/video?
Alternatively I think it's be insane if you somehow kept it hidden from Fubuki despite being in contact with Cover Corp and rebroadcast one of her live streams, live in real time, in Times Square and SOMEHOW managed to keep the chat from spilling the beans because she'd absolutely have a nervous breakdown and spill spaghetti if she found out mid-stream.
