Sometimes the safest place for a document you want to preserve is in clear view. At least the old "out of sight, out of mind" adage won't apply. If you decide, for example, to hang on your wall the weathered playbill of your great aunt's first -- and only -- theatre appearance, enlist the aid of a professional framer. And we're not talking that helpful young man in the local discount store's frame section, either. Ask around until you find a professional framer with experience prepping museum-quality documents for display. That way, he or she can use the tricks of the trade -- like special conservation glass for blocking ultraviolet light and acid-free backing -- to ensure your document's place in family history.
