In May of 2021, I decided to seek out an address for Kurt Archer. I sent him my card and the following letter.
Kurt signed a 1991 Classic Best card #223.

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.Derek signed a 1994 Fleer Excel card #89.
