Now, on to the reason I'm writing this. I dug out a handful of 2012 Topps Heritage from this guy's box in a futile effort to build my set. When I returned home and began adding my new cards to my Zistle account, I noticed one card didn't quite fit in with the rest of them. Naturally, I began researching the variations and intentional errors Topps loves to include in Heritage. Nothing showed up for this particular card.
Readers, please correct me if I am wrong, but I believe I have stumbled across a legitimate error from Topps, meaning this was not intentional.
The card in question is shown below next to the errorless card.
Notice anything? Of course not. It's because the error is on the back...
