This corner had been covered by a piece of paper that MROSD made that gave my name and information about the picture. The part of the picture underneath didn't fade. Other corners had clear plastic over them (to hold them down since the picture was wider than the mounting bars). Those corners also didn't fade, even though the plastic was transparent. Hopefully the lamination on the new print we've put up will give the same protection.
[The card in my hand is a gray card used to ensure accurate colors in this photo.]
