A guy on a card collecting Facebook group I'm a member of recently opened a box of 1997 New Pinnacle Baseball. The card pictured below was included in a pack. Interestingly, it was on top of the same card in normal condition. Guy was nice enough to send it to me for free for my Grace PC.
The weirdness includes the diagonal cut, really rough edges on all sides, another smaller diagonal cut on the left edge, and clear tape over half of the card front with the Pinnacle logo printed on the tape in black. The tape wraps around the edges a little and folds over just a bit to the card back along the bottom diagonal cut. If you look closely on the front, you can see the tape extends halfway up the card to just above his elbow.
I have no clue what was going on here. Just weird that this scrap made it into a hobby box pack. Who knew Pinnacle Branded Tape was a thing? Weird, wild stuff.
