These one of a kind 31 MIKE PIAZZA DR Street Sign are made of heavy, galvanized steel. You won't believe how heavy these signs are. The deep embossed letters create a classic 3-D look and the signs are finished with baked-on enamel paint in official team colors. Proudly show your team pride in your office, sports room or even outside. One of the few items you can buy that is still Made in the USA.
