Cotton RagMat Museum matboard is the natural choice when the highest levels of protection are required. For over 1500 years cotton has been both the courier and curator of history. Priceless documents such as the Gutenberg Bible, Shakespeare’s first folio, and the U.S. Constitution and Bill of Rights exist today because they were printed or penned on cotton paper. The time-honored practice of making matboard with cotton paper is still employed by Crescent today. It is rich in tradition, requiring time, skill and great attention to detail.
The quality of cotton RagMat is simply unsurpassed, it is preferred by preservationists and museums worldwide and has been trusted by artists and historians for centuries and now it is available only to the art and framing professional.
