The advertising, recognition and identification marker includes, among other elements, a disc-like base unit, a disc-like insert unit, and affixing devices and applied adhesive materials. The disc-like base unit has a top surface, a bottom surface and an angular lateral bevel. The bevel bears advertising, recognition or identification information. The disc-like insert unit has a flat surface to bear advertising, recognition or identification information. The affixing devices and applied adhesive materials permit the insert unit to be affixed to the base unit and the base unit to be affixed to the item.
