A mural is simply the name given to a picture that has been painted onto a wall. A window mural can best be described as a picture of a view through a window frame.
Whilst the mural can be painted or transferred on to an actual window most times they are literally a picture that gives the impression of looking through a window and its frame. The French call this style “Trompe l’oeil”, which literally means “to fool the eye”. With window accent murals, even if you’re living in apartment in the middle of a city, you can have an apparent view of just about anything you want.
