My dad's birthday is June 14th. He passed away on August 31, 2020. For his first birthday without him,  I came up with another TTM challenge for myself. This one I called "Dad TTM Project."

Derek Wachter

On September 10, 2020, I decided to go through these 2 alphabetical boxes of baseball cards and pull random cards out. I would then look to see if I could find a mailing address online to send a card to.

I ended up writing and mailing out 11 letters that day. All addresses that I looked up myself, not listed on an autograph database, as far as I could tell.

I found what looked to be a legitimate address for Mr. Wachter, so I wrote him a letter and included my card.

219 days later my card came back signed.

Derek signed a 1994 Fleer Excel card #89.

Don August

On September 17, 2020, I wanted to do something different with my TTM requests. I thought it would be fun to mail cards to players with the same last name and see which one comes back first. The players were Don August and Sam August. No relation between the two, as far as I could tell. I called it "An August Race in September."

Don August's address is well known, as he is very fan-friendly. Sam August only played in the minors, so his address isn't listed on autograph sites, so I had to locate it myself and hope that it was right.

Don won the race. Twelve days later my card came back signed. He even included a note.

Don signed a 1989 Score Rising Stars card #83.
