Actually Steve, three of the Beantown find Old Mills I purchased from you did exhibit light "wet sheet transfers" (or "humid card transfers". They weren't nearly as pronounced as the example Iggy used to start the thread and probably not the kind of thing you'd notice if you were going through 1000's of cards, nor is there any way of determining whether the effect was caused by how the sheets were stacked in the factory or by the cards being tightly packed in tobacco boxes (as you described), but I had simply assumed it was the latter.
