The Wolf Ridge Farm sign is made of SF3 sign foam, lasered out and painted.  The signposts are motised and grooved so that the top plate is removable.  This allows the sign to be changed in the future as needed.  It is actually 5 different 2 sided signs with the main sign being 24 by 18 inches, the size of the laser bed.  I have to drive by this spot on my way to work every day so it had to look good.
