Glenn Dishman

I met him at a Minor League game at TD Ballpark in Dunedin, Florida in 2023, when the Jupiter Hammerheads, for whom he was the pitching coach, came to play the Dunedin Blue Jays.

Glenn signed a 1995 Fleer Excel League Leader card #7.

Earl Johnson

I was randomly going through my box of cards and stumbled across this one of Earl Johnson. I always liked this card and thought it would look great if it were signed, so I decided to look online to see if I could find an address to send it to. I discovered that he was a lawyer in Michigan.
So, three days after Christmas 2018, I sent Mr. Johnson an autograph request through the mail to the law firm where he worked.

Ten days later my card came back signed. He was also nice enough to include a note back.

Earl signed a 1995 Fleer Excel League Leader card #11.
