Back of autograph cards
 

Saw a story on this 1/1 signed refractor of Otani on Sports Collectors Daily - here's the eBay listing: https://www.ebay.com/itm/2018-FINEST...d=163085325883

Regardless of what I think of the front of the card (which is hideous), the back of the card has almost no difference from a redemption card. It's like buying half a card and half a redemption card, and regardless of it being a 1/1, I wouldn't want a card like that for my PC. Any auto cards I've bought have to have a nice image on the front and at least something of substance on the back.

But clearly, I'm in the minority as the Otani seems to have sold quick for some pretty big cash...
