I can't seem to be able to sleep at all tonight. However, with my restlessness, I've come up with an idea I want to try with the paper... I want to run a black light over it. Maybe there is something there, just not visible immediately to the naked eye. I don't own a black light, so tomorrow I'll borrow one from a friend. I'll post in the near future on my findings with it, or anything else I may come up with.
