And the
winner/loser is lucky/unlucky #3...
I know it's an old label and all, but it looks like the only one with the O/C designation is perhaps the best centered of all eight cards. At first glance it is clearly better centered than four of them. And take a look at the closest point any part of the image comes to the very edge of the card in each of the pictures. Arguably, the space on #3 is the widest.
