Celebrate every 2nd Place, April 22nd (Earth Day), and more with these Black ND Symbol Yard Signs. The two-letter single yard sign helps make displaying outdoor messages on school lawns a little easier! These exclusive yard signs are made of a sturdy, plastic corrugated material and are available in 12" high x 20" wide and 18" high x 31" wide sizes; both sizes include 15" wire stakes for easy display. Mix and match these black and white ND Yard Signs with other Symbol, Number, and Letter Yard Signs (not included) to create a variety of outdoor displays for Field Day, holidays, countdowns, graduation, and more. Each ND Yard Sign comes already die-cut--all you have to do is push the wires into the sign and then push the entire sign/wire a few inches into the ground. NOTE: The plastic corrugated material of these Yard Signs is water-proof and weather-resistant, so it is durable enough to use in almost any type of weather. NOTE: A minimal amount of assembly is required. No set-up charge!
