100th Day of School. Fourth of July. 5th Grade. These are just a few messages you can use Black TH Symbol Yard Signs for on your school lawn. They help shorten any message, so you don't have to purchase every single letter! Mix and match the TH Yard Signs with other symbol, number, and letter yard signs (not included) to create one-of-a-kind outdoor messages. Display them on any of your school's lawns, they will make a big impact on parents, students, passersby, teachers, and more. Made of a sturdy, plastic corrugated material, the Black TH Symbol Yard Signs come in 12" high x 20" wide and 18" high x 30" wide sizes; both include 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. Use your Black TH Symbol Yard Sign(s) for game days, holidays, Field Day, countdowns, graduation, and more. NOTE: A minimal amount of assembly is required. No set-up charge!
