I was able to slay another one of my white whales this week when I added a 2008 Upper Deck Baseball Heroes autographed purple parallel, which is serial numbered 1/5.
It's a great looking card and I love the purple background. It's a regal color and is fitting for such a low numbered card.
I had no clue that there was a purple #/5 parallel in this set until the moment it popped up on the bay. Until that point, I assumed that the #/10 red parallel was the lowest numbered card. Sometimes it pays to constantly troll the bay.
The rainbow is coming together nicely.
