You viewing Paris From your bedroom’
You viewing it through a window in your room
One of those posters that are of a photo at night ,with all the lights of Paris shining bright would be good.
but anything you like will do

What you are going to do is make a fake" window"
on a blank wall where there is no window at all.
With all the other windows curtains close
You will be able to view Paris
From this window

Use a simple curtain rod
or just pin up the elegant cloth that drapes above the window and the hangs down the sides of the poster(window), so the top & edges of the poster are hidden.
Then make a simple shelf ( maybe 3" deep and the width of the window ) at the bottom edge of the poster.
This is the window sill and can be used to set a candle upon.
Now all 4 sides of the poster hidden,
3 sides by the flowing curtain and the bottom by the fake window sill.

If you mak the "window" large enough
you place a very small round table ( 20")
In front of the window with a small chair.
And view Paris While drinking your coffee or tea.
For me it would be some wine with bread & cheese.

Did you see it ?
Or not ?
