'15 Topps Jason Heyward #181 "Waving" Variation.
Acquiring this card caused me to have page order angst. Until now I had avoided putting the "sparkle" variation into the binder. But I figured with this card it was time. I have a thing about base and parallel pages being identically arranged. I don't consider the variations to be inserts so I've decided to keep them with the base team set. That throws off the aforementioned symmetry that I keeps me sane. Also, should this card come before or after the "sparkle" variation? (I still don't understand the hidden gem thing) These are the things I think about at night.
At any rate I'm happy to have all three Heyward cards in my possession. I still have a few more flagship variations to track down. Then I can turn to more pressing matters, like figuring out all the Update variations.
