Toy Store Room Box

I came across this room box at an estate sale this week:

 It is housed in a nice wooden box and has a framed glass door that closes over it.  The scene is shown above - a small boy looking into a toy store window.

Here is the view inside one end.

The view looking the other way shows a cash register and a small white mouse 

The room is jam packed with all kinds of items, some store bought and some handmade.  I suspect it must be from the late 1980's or early 1990's?
