Yep, for me too Gary.
The pencil makes it hard work on the eyes.
The month is unreadable, but the date looks like the 20th, possibly 29th.
I believe I can just make out the notation top left before the date that the game was played at the Union Grounds - home of the Mutuals, and the Athletics played there on June 29th so I think that the most likely date.
Either that or I am reading those first couple words incorrectly.
If I was better reading a box score I could probably find the schedule and be sure....
