That is scary to think, but I believe it can happen to paper items too. I do not collect baseballs, but have a couple dozen I have picked up for one reason for another. I will go to my death still complaining about the certain UD Sweet Spot balls that faded. Aside from several Garvey cards that have faded almost to nothing, I am victim of a Mike Marshall glove card /25 that is bleeding/fading into nothing. Had I known or had the slightest clue, I would have paid extra for the baseball versions. They seem to have survived. The gloves, at least mine, are not!
