One way to get your message across to promote your brand is by using a billboard. Even though most of the billboard features a single billboard to put more emphasis on our design, a triple billboard featuring three billboards at the same time can do the trick for you.
Here is a great triple billboard mockup in which you can showcase your designs as realistic as possible. Plus, as triple billboards seem more, it brings you on an urban and civil style. Thanks to smart object layers, you can simply insert your visual content through the billboards and enjoy the immediate result.
