Hello: I am a collector of historic documents and would like to know the best way to frame my material. I would also appreciate references for qualified framers in the NY/LI area as I have been very dissatisfied with the results of all of my local framing "experts" who advertise "museum quality" and even conservation framing.. I also have a specific question. How important is it that paper material remain exposed to air? I've seen some wonderful lucite items sold by Capital Plastics which is used by Currency collectors, but it seals the item air-tight. Is this safe to use for documents? Thank you in advance for your reply.
