24 in by 24 in (600 mm by 600 mm) Alaska highway shield, made to the specifications of the <a rel="nofollow" class="external text" href="http://www.dot.state.ak.us/stwddes/dcstraffic/assets/pdf/asds/e_i_l_m/m01_005.pdf">2003 sign design specifications</a> (sign M1-5). Uses the <a rel="nofollow" class="external text" href="http://www.triskele.com/fonts/index.html">Roadgeek 2005 fonts</a>. (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.)
Note: the ALASKA might not be perfect, as the specs do not specify the font, so I had to copy it from the PDF.
