Joe,
Here is an article referencing the OAC. It is about Lacrosse but shows you that OAC existed in that region.

I found another photo in front of a house with some references but the logo is different.

OAC could also mean Ohio but I think upstate NY is correct for the photo you have.
Sorry I could not be of more help.
