I'm not sure what type of authentication you are looking for. With the address being on a label, it would generally be that of the photographer/studio, rather than the subject. It may be more productive to research the subject of the photo if this is not a portrait photo (which are ten for a dollar lately).
I'd first start with a search engine like google.com, making an entry like this:
+'address' +'name of city' +'name of state'
If anything interesting happened at that address, it's generally noted on some sort of web page. You can clip out the address number if you want more information on the area, and perhaps locate a business name that way (ie, 'John established his studio on Main Street in Anytown, Your State, USA in 1912'
