In February of 2021, I decided to seek out an address for Jim Baxter. I sent him my card and the following letter.

I met him at Jack Russell Memorial Stadium in Clearwater, Florida in 1996, when the Pittsburgh Pirates came to play the Philadelphia Phillies in a spring training game.
Dan signed a 1993 Classic Best card #222.
I met him at a Minor League game at Dunedin Stadium at Grant Field in Dunedin, Florida in 1994, when the Fort Myers Miracle came to play the Dunedin Blue Jays.
There was a stipulation before acquiring his signature. I had to get him a soda from the concession stand. I agreed and he handed me some money.
Rich signed a 1991 Classic Best card #200.
