Last year, I got a TTM success back from Taylor Walls. I pulled this nice 2021 Panini Chronicles of Walls and really wanted to send to him again. So, I sent the card, along with a 2021 Topps Update and sent them to Spring Training. The cards came back signed with a dead Sharpie, but they're still signed. I'll take what I can get.
The 2021 Update came out worse than the Chronicles, but I can't complain. Especially with how tough it has been to get Spring Training TTMs back these days.
I mailed to Walls on March 15 and got the cards back on April 9, for a 25-day TAT.
