Measures 18" Square Diamond Shape Exceptional authentic vintage road construction warning sign featuring classic diamond shape with bright yellow background and black lettering. This heavy-duty metal sign shows beautiful aged patina with authentic road wear and weathering that collectors prize. The sign includes original reflector buttons (cat eyes) in the center, adding to its authenticity and visual appeal. The bold "TRAVEL AT OWN RISK ROAD REPAIRS" message represents early American highway safety signage when road construction warnings were more direct and informal than today's standardized DOT signs. Perfect mounting holes intact. From the Lynn Smith warehouse collection - an outstanding example of vintage transportation infrastructure memorabilia.
