Please show me a sign...

Here is the view of the building from the bus stop across the street where AEL will be located. We'll be on the top floor (3rd) at the right corner of the building.

I'm trying to decide what type of sign to use and where to locate it. I'm not sure I can light the sign at night because there's no electricity outside. Maybe I can put some lettering on the side window (upper left window of the shaded side of the building). My wife suggested that and also putting Christmas lights around the window border (good idea honey)...

I think I also want something on the balcony side facing the street. Check back to see what I come up with!
