Need a sign that’s not spray-painted on an alley wall late at night? Don’t need to render Britney Spears on a five-story LCD? Maybe what you need is a temporary sign. Low cost, colorful, quick, and easy to acquire, a vinyl sign just might do the trick. This four-foot-wide, eighteen-inch-high banner was done the same day as ordered and cost about $80 including tax. Probably my favorite of temporary signs though would be the freeway overpass with chain link fence where someone presses paper or plastic cups into the mesh to spell out a personal message.
