4 Strikes and You're Out!

Patent date of Oct. 12, 1886. From before the last rule change, I believe the rules changed around 1888-1889. Very rare umpire counter, clean but with great game use.

I would sell this to a great caretaker, can PM me.

A curious one-of-one artifact is this 1995 Polaroid photo of model Bridget Hall shot by famed French fashion photographer Gilles Bensimon. This was a lighting/colors test photo during the shooting for her swimsuit calendar. Polaroids were often used for such on-the-spot tests as they could be developed at looked at on the set. And each Polaroid is unique. Polaroid makes one and only on photo per image and the one photo is developed seconds after the image is shot, so a Polaroid as close to self authenticating as a photo gets. Unlike photos printed later, this photo was literally on the set with Hall.
