As a general rule, you would like the piece away from the glass. That being said, it's amazing that this stuff has survived for a hundred years without any protection whatsoever, so who knows. Baseball cards are certainly right up against the surface in any type of sleeve or a screw down. Then they stick them in those nasty little plastic tombs which I don't think are the most "archival" setups going. My entire collection never sees natural light and is in a controlled climate. Good Luck.
