Many teams have their own card sets; MLB teams have had card giveaways for decades, and Japanese teams have their own sets.
The BayStars sets seem to be comprehensive, containing every player on the roster at the time of issue. I call these "B*Spirit" given the notation on the backs. This also distinguishes them from other BayStars sets; the past two seasons saw team-issued (or at least, team-sanctioned) pack based sets. (I opened a box of one of these a couple months ago; they are technically issued by Produce216, but don't carry TIC logos or copyrights.)
I was happy to grab a big lot of cards from the past several years in hopes of finding some Rami-chan singles I didn't have and filling in some gaps. I was successful on both fronts; you'll see the Ramirez cards included below, and for several of the years, I grabbed one card from the stack for the type collection.
Note that, to save space, I've left these images pretty small. But you can enlarge them by clicking on them, or right-clicking and opening in a new window for the full size window. Of course, if you're on mobile, that might be more difficult. Sorry.
I still feel 2016 is the best design of these four years. What do you think?
