A watermark is a distinctive design or pattern visible when paper is held up to light, created during the papermaking process. In rare book and document dealing, watermarks are crucial for authenticating old documents, dating papers, and determining their origin. They're like fingerprints for paper, helping dealers and collectors verify the age and authenticity of books, manuscripts, and historical documents. Understanding watermarks is essential for professionals who buy, sell, or authenticate valuable paper items, as they can significantly affect an item's value and historical importance.
