Cardinal Matt Carpenter’s grateful personalization

I spotted some great St. Louis Cardinals candid photos on the team Facebook page Wednesday.

Most of all, there were some awesome inscriptions on the photos.
Sure, the regular season limits active players to a “best wishes” or “good luck” personalization.
Seeing the Matt Carpenter pic made me ask:
does anyone ever add “thank you” to their autographs?
Two generations prior, celebrities of all kind would thank a fan in writing when giving an autograph.
Readers: ever gotten a “thank you” autograph? I’d love to know more.
