Debra JohnsonLeslie -- It seems from the comments above that the 'light' idea is the least invasive. I know a bleach solution would surely kill it, but I can verify that additional moisture on these cards can cause surface creases and/or lift portions of the top layer.
I don't know the best thing to do. I mainly just wanted to let you know that since the cards have been in a temperature-controlled environment for seven months now, I've seen no additional growth or damage. Mold spores need moisture to thrive, I think, and the cards have been dry for a long while now. Air conditioning is the 'anti-mold' agent in south Mississippi.
When you take a look at the card, if it's more than you want to take on, just send it on back.
David -- Thanks for the wealth of information. Had no idea light was used to clean items and air. Will the book be available to the general public? Thanks for posting.
