Here is an example of the type of print defect I'm talking about. Again, sorry this is an 'out of catagory' post, but I felt I'd get the best results for my question based on the expertise of the contributors of this section of the forum.
1964 Philadelphia Bob Lilly: Note the dark horizontal line just below the white top border. I've seen this line on every example of this card I've seen. Similar lines can be found throughout cards in this set, but I can only speak for this one in terms of 'every' card.
