Joseph Sauer invented one of the last catcher's gloves before the pillow type mitt became the norm. His design featured a layering of padding and leather to the pocket and an extra layer of leather over the separate finger stalls to protect the catchers fingers. Below is one of Sauer's patent illustrations from 1888.

The Goodwin & Co. cabinet photos of 1889 provide a good look at that early era because most of the photos are shown with players and their equipment. The photos also provide a unique look at a very brief time, maybe a year or two, when the Sauer's glove was used extensively and before the pillow mitt took center stage in the 1890's. The photo below is of Andy Sommers and you can see the thick padding and dimpled attachment points in the pocket of his glove.

The back of Joseph Sauer's glove was interesting in the wrapping of chinchilla leather around the fingers and attaching at the back of the finger stalls.

The 1889 cabinet photo below is of Hy Ebright. You can just make out the wrapping of the finger stalls on his glove. It's also intersting how large the catchers glove became by 1889.
