New England Interstate Route shield. Uses the US Highway Old Style font. (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 Yellow 116), converted to RGB by [2].
Of course, as this type of sign was only uses in the 1920s, and was mainly painted on telephone poles, everything about this SVG is approximate, as I do not have specs for it.
