Also I think you should archive and store this historical BTC item better than in a frame. I am sure those clips hodling it will leave a mark.I cringe when I look at them.
Also exposing paper to light am sure does not help either. Stamps should never be left exposed to light..so neither should newspapers.
This article might help you in archiving it properly.
Had no intention of getting involved with all this drama, BUT I feel compelled to encourage you to listen to Krogoth here. The clips make me physically ill to look at.
