750 mm by 750 mm (30 in by 30 in) New Mexico state road shield, made to the specifications of the PS&amp;E Standard Drawings, which specifies a 30" by 30" shield for 3-digit roads. Pictures of actual shields were also used for reference. Uses the Roadgeek 2005 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.)
