Of note is the Immaculate Cleats Jumbo Card of Corey Seager. Unfortunately, this card has yet to make an appearance online, but it represents something very new to Baseball card collectors. It featured a jumbo sized relic piece of his shoe. Based on what I've seen so far, these cards are the coolest things I've ever seen - and I'm not a huge fan of relic cards. From what I understand, card manufacturers have been making cards like this for several years, but this is the first time its been done for Baseball. I've included an example of one of these cards below.
