I guess I should have at least pointed out that the date is written in month/day format.
It's actually 4/22
The ball was signed/inscribed from umpire Billy Evans to a broadway actress (Edith Luckett, mother of Nancy Reagain) who lived in DC. Billy Evans was the home plate umpire on 4/22, NY Highlanders at Washington. Walter Johnson pitched for Washington in a 3-1 loss. Notable in the game was WaJo's accidental beaning of Birdie Cree.
