UV energy isn't the only type of energy. Enough of visible light energy can fry anything. Thermal damage is what I would say could do in the retina. Don't forget you have a 60 diopter magnifier sitting in front of the retina.
Yes that makes sense. It's a good way to look at it.
Anyone know the answer to the 2nd question?
If there are absolutely no windows, and the posters were never exposed to natural light sources from the sun, then my guess would be that moisture (from the basement) can be the cause.
I think it might have to do with the fact that moisture can carry contaminants and pollutants to another source, and over many years, can degrade the item.
I looked into this one and I think that oxidation may be a major culprit. Newspapers yellow and age from oxidation, mabey fading is also a result of this?
