1st Day of School. First Place. December 31st. These are a few examples of how to use your ST Symbol Yard Signs on your elementary school's front lawn! Get creative with these Yard Signs, and other outdoor décor we offer, to create fabulous lawn displays for holidays, Field Day, school spirit, countdowns, graduation, and more. The black and white ST Symbol Yard Signs come in two convenient sizes (12" high x 17" wide) and (18" high x 26" wide) that are easy to display and mix and match with other Symbol, Letter, and Number Yard Signs (not included). Each black ST Yard Sign features a white-outline and comes with 15" wire stakes for easy display. The material is both water-proof and weather-resistant, so the yard signs are sturdy enough to withstand most types of weather. NOTE: A minimal amount of assembly is required. No set-up charge!
