Slightly OT, but I have a 1910 OAL ball signed/inscribed by umpire Billy Evans to an actress who lived in Washington DC (Edith Luckett, aka Nancy Reagan's mother). There is a faint inked date next to the 1910 stamp that, best I can tell, reads 4/22...the date Walter Johnson hit Birdie Cree, NY vs Washington, at Washington. Billy Evans was the home plate umpire. Zero chance of ever knowing for sure, but still fascinating to entertain the idea that this was the ball that did the deed.
