I am very grateful when I get a tip that a new Cutch card is available that I previously didn't know about.
A coworker tipped me off to this.
It's another 2017 Topps Transcendent Party 1/1.
I don't know the backstory on these, but I can only assume they were a prize for last year's Double Play Rip Cards. My guess is that no one claimed the complete set by sending in their redemption so Topps had these cards "boughtback" and turned into 1/1s for the exclusive party.
