The Ernie Banks card is #253, which is the same number as Brandon Drury. The Sandberg card is #306, sharing the card number with Jon Lester. .Sandberg and Lester are both Cubs, but I have no idea what the connection is between Banks and Drury.
There are also photo variation cards for several of the current Cubs, but I'm not chasing those any longer. I need just one card for each of them.
All of the other Cubs cards from Series One will be coming from brentandbecca. I'll have to wait a bit for them. When I first started buying from Brent, I'd have the cards within a few days of the product release. As he has gotten bigger, it takes longer for the cards to arrive. I believe he is opening 90+ cases, so it takes a while to open and sort all of those cards. I'm not complaining, just explaining. Brent's prices, when buying everything from one seller, especially, save me a bundle. It's worth the wait.
