A few weeks back I showed off the Gold Label parallels I had acquired to that point. That post inspired me to track down the two missing non 1/1s of the rainbow.
While the rainbow isn't complete yet. I picked up the missing Red Class 3 from 2017 Gold Label of Andrew McCutchen I needed. Only the Black Class 2 (not numbered SP) and all the 1/1 Golds remain.
Chalk up another nearly completed rainbow.
