Summary
DescriptionUS 80 (AZ historic).svg
English: 610 mm × 610 mm (24 in × 24 in) U.S. Highway shield, made to the specifications of the 2004 edition of Standard Highway Signs and modified to match historic route shields used on Historic U.S. Route 80 in the state of Arizona. (Note that there is a missing "J" label on the left side of the diagram.) 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.)
