Showcase a clever ad on this poster mockup that is acting as a mat on the top of the stairs of the mall. The ad is set right at the top of the stairs and stuck to the ground. You can see a family walking down the steps in the background. The stairs have a glass hand rail. The floor is made up up tan square tiles. The poster mockup will hold an image of 1200x1900px. This is the perfect place for a clever ad design.
