I've just been spending the day modeling the decorative trim for the escalators. I haven't finished making the rail for the décor, but I'll get it done soon! In the final version there will be 3 layers of wallpaper on the boxes with most of it peeling showing the other layers, but the 1966 version of the prop should do fine for the greybox.
The more I work on this map, the more it's looking like a darn IKEA store...
