Date and Origin of 1800s Cabinet Photo

[Leon]

A cross between a card and a photo..(probably more a photo). This was listed on the bay as being from an estate from Racine WI. The estate of Sadie Duncombe and this is what it said below. Her name is on back as can be seen too. Any ideas on the team though? Or any of the other players? Thanks in advance..

"This auction is for a really nice and very rare antique 1900-1910s era cabinet photograph that depicts a baseball team once located in Racine, Wisconsin. The players are all identified at the bottom including Duncombe who was the relative of the famous Dr. William Duncombe of Racine. This comes from his families estate and it's guaranteed old and original. Back in these days a lot of the large companies like J.I. Case had their own baseball team and they all competed. Not sure what the A stands for on their uniforms. Measures about 10" x 8" and is guaranteed as described!"
