Abstract: A flexible fade resistant posted marker sign based on a flexible substrate and fade resistant coating that can bend to lock onto a studded flanged post by positioning the sign ends between the studs on the post with the body arching across and over middle studs on the post with the sign being wide enough to span across the flanges of the post and be secured with wire passing through holes positioned to place the wire at the sides of the width of the post to inhibit vertical, horizontal, and twisting movement of the sign while still maintaining a continuous center section of the sign for use as a colored warning blaze.
