24 in × 25 in (610 mm × 640 mm) California State Route shield. The outside border has a width of 1 pixel and a color of black so it shows up; in reality, signs had no outside border.
Made to the specifications of the 1971 Caltrans sign drawing (still in use). 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.)
