Just how and where a business can employ a wall mural is up to that individual business. The benefits of wall murals are many and they all vary depending on the context in which they are used. When used externally, wall murals act as memorable identifiers. If you manage a bar with a wall mural of a giant purple monster on the side of your building people are going to remember your bar as, if nothing else, “that bar with giant purple monster on the side of it”. They will also definitely know they’ve found your bar when they walk past it and see said giant purple monster.
