600 by 600 mm (24 by 24 in) Interstate shield, made to the specifications of the 2004 edition of Standard Highway Signs (sign M1-1). 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.) Colors are from [1] (Pantone Red 187 and Blue 294), converted to RGB by [2]. This image has a black border of width 1 mm to contrast with the light backgrounds of many web pages; the border is not part of actual signs.
