I've never seen that, but then again, I don't see a lot of white whales. I can't imagine that it's unheard of considering the production process. If it were me---and I'd wait to hear what others have to say---I'd put a little bit of glue in there to maintain the integrity of the card and just call it good.
Always looking for Verlander, Cabrera, Maybin, Mike Stanton (marlins), and Avisail Garcia.
