I passed a sports card kiosk in the mall the other day, and was intrigued by the neat little plastic cases they sell to preserve your treasured sport cards. There's a heavy-duty plastic case, almost a thin box. but there's also a lighter plastic envelope. It would seem that there must be some way to use these to "laminate" your operating cards. Put your car cards in them? Put your waybill cards in them? I haven't really thought this through, but was wondering if anybody has tried this??
