I am guessing these are photos from a visit to one of this young couples grandparents. Maybe the grandparents are meeting their grandchild for the first time. One commenter on my Flickr said that the clothing looked like the styles in the Ukraine in the mid-nineties.
If this is grandpa he doesn't appear to be very comfortable holding his grandchild. I do wonder why the pictures were never developed and I imagine that may always remain a mystery to me. Here is a gallery if you'd like to see more of these photos.
Found Film from the Ukraine
Here is the camera that took the photos. I admit that I got it because it is red.
