Apparently, Panini has them too.
Here is the back of Ryne Sandberg's 2012 Panini Cooperstown card
So how long?
I asked Mrs. WW to look for the error on the card. Now granted, she's married to me and has had to endure a lot of Cubbyness over the years, but she doesn't have a head filled with Cubs minutia like I do.
It took her 15 seconds before she said, "South Siders??"
So what's more messed up...Upper Deck moving Billy Williams to first base or Panini moving the Cubs to the South Side??
I've offered my proofreading services to Topps, but they've yet to take me up on the offer. I'll put it out there to my friends at Panini, too---I'd be more than happy to look over any Cubs products you make, to ensure you don't make yourselves look like fools.
Yes, I know that I just made a mistake---do you think any card manufacturer would have caught the mistake, too??
