Our "Wrenchtwister University" tin sign brings a bit of humor to your home or business. These vintage looking metal auto repair signs are much larger and more impressive in person, made from heavy gauge tin, and feature colorful, fade-resistant retro graphics and pre-punched holes for easy hanging. As always, a portion of your purchase is donated to the Smile Train, a charity that performs reconstructive facial surgery on children around the world (check our home page for an up-to-date smile count).
