600 mm by 600 mm (24 in by 24 in) Business Spur shield, made to the specifications of the 2004 edition of Standard Highway Signs (sign M1-3). Uses the Roadgeek 2005 fonts archive copy at the Wayback Machine . (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.) Colors are from [1] (Pantone Green 342), converted to RGB by [2] . The outside border has a width of 1 (1 mm) and a color of black so it shows up; in reality, signs have no outside border.
