How to you tell if a photo is 1st generation or later
 

Hi I picked up a photo of Ruth and Gehrig when they were here in Albany. I am not sure if its 1st generation or later. I see that there are alot of experts out there. Any help would be appreciated. Thanks

Tony, just scour related posts - there is tons of information about this subject, in older posts.

thank you Scott. I will do that

What, if anything, does it say on the back? That's a good start.

The experts will be a lot more help if they can see the photo in question...
