24 in by 24 in (610 mm by 610 mm) cutout U.S. Route shield with 10 in (250 mm) numerals, made to the specifications of the 1961 MUTCD . Uses the Roadgeek fonts. (United States law does not permit the copyrighting of typeface designs, and the fonts are meant to be copies of a U.S. Government-produced work anyway.)
