In April of 2021, I decided to seek out an address for Gordon Amerson. I discovered that he was the superintendent of a school district in California, so I sent him my card and the following letter.
27 days later my card came back signed and he included a signed business card.
Gordon signed a 1994 Signature Rookies Draft Picks card #73.
