A 1/2-digit Maryland state highway route marker (shield) template.  I created it myself using Inkscape.  It should not be linked to directly, it should only be used to create new shields for 1-digit or 2-digit Maryland state highways. (see also: MD template wide with one.svg, MD template wide no one.svg).
