I added some more cards recently by sending TTM to Taylor Clarke at Spring Training. I got the above 2017 Topps Heritage Minors and the below 2018 Bowman signed by Clarke very nicely with a blue Sharpie.
Clarke (b. 1993) made his major league debut with the Diamondbacks last year. He went 5-5 with a 5.31 ERA and 68 strike outs.
I mailed to Clarke on February 10 and got the cards back on February 28, for an 18-day TAT.
