This invention relates to an article comprising a transparent stack of sheets that may be applied, for example, to protect substrates such as glass or plastic windows, signage or displays. A topmost sheet can be peeled away after it is damaged to reveal an undamaged sheet below. The invention also relates to the protected substrates and a method of protecting substrates such as glass or plastic windows, signage and displays from vandalism or other surface damage by adhering the stack of sheets to the substrate to be protected and subsequently pulling a topmost sheet away from the stack after it becomes damaged.
