When 2018 Panini National Treasures Baseball was first announced, one of the focal points on the production information sheet was a dual cut signature book card featuring Babe Ruth and Lou Gehrig. Besides the obvious fact of boasting autographs from two of the biggest stars to ever play the game, this particular card had a couple of additional things going for it. First, both of the signatures were together on the same document, not two separate ones embedded into the same card. There were also uniform and bat swatches from both players.
But this was a card on a sell sheet. These are usually just digital mockups, right? Yes, but the 2018 National Treasures Babe Ruth, Lou Gehrig booklet is real and as advertised.
