mystery solved, I did more searching on the internet. I found that the Azo post card dates between 1904-1918. I had my suspicion that it may be a Flint Michigan team. I found a website that has the same photo, different post card, but it identifies them as them as "Flint Base Ball Team" they played at Athletic Park in Flint, Mi. I'm going to do a little more digging, maybe I can identify the individual player in the photo.
thanks for all of your help!! It's much appreciated
