[Old Hoss]

I have recently picked up a few old scorecards (like this 1891 American Association scorecard of a game between Louisville and Cincinnati), and am wondering how other collectors store their scorecards, especially the (usually) small 19th century ones.

Several of mine have come in a hard plastic sleeve. Do you leave them in such a sleeve? Do you have another way of protecting them? Finally, do you have any other storage tips?

Thanks!
Charles
