It's been forever since my last post. I've been busy... again. Let's see if I can get caught up on 2017's sets before 2018!
Similar to the 1st Version set, 2nd Version has some "secret" variations - one per team. The Yamasaki card above is a variation I pulled from a pack.
Gold Signature parallels are serial-numbered to 100 copies.
Red foil is serial-numbered to 25, while green foil signatures are numbered to only 10.
BBM's checklist states that these cards are available in parallels of 200 and 50 cards as well as autographed versions. Additionally, one of the subjects has a secret variation, bringing the total in the set to fourteen.
