These signs are full-color, multi-scale, reproductions of actual signs from a variety of periods. Simply cut the decal from the sheet, lightly sand the back and then soak and saturate sign in diluted white glue mixture. Next, press and smooth down sign to surface using your fingers. Let dry one full day. Signs can also be 'toned-down' a little by weathering. Quik-Signs include more comprehensive installation instructions!
