English: 750 mm by 600 mm (30 in 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]. 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.
I, the copyright holder of this work, release this work into the public domain. This applies worldwide. In some countries this may not be legally possible; if so: I grant anyone the right to use this work for any purpose, without any conditions, unless such conditions are required by law.
