In design, three of anything creates the most pleasing look and these custom posters follow that rule beautifully. Printed on tear-resistant polystyrene for durable, kid-friendly use, they showcase three favorite photos in a row, making them great for kids' rooms and dorm rooms. The medium-size 24" x 18" layout is horizontal, and holds three vertically oriented photos. You can choose from over 70 colors for the background to match a room or favorite color. Plus, the text is editable, so you can personalize your custom poster with a name, inspirational message or anything you like. Weather resistant for short-term outdoor use, they are also great for birthdays and graduations!
